chore(lint): adapt to staticcheck v0.8.0 under golangci-lint v2.13.1

golangci-lint v2.13.0 pinned honnef.co/go/tools v0.8.0-rc.1, whose
staticcheck never terminates on internal/web/service/tgbot: the run pins
~520% CPU with RSS climbing past 700MB rather than deadlocking, so it
reads as a hang. controller/, job/ and service/... only appeared stuck
because they pull tgbot into the analysis graph. v2.13.1 ships the final
v0.8.0 and clears it — that package goes from unbounded to 0s, and a
cold full run to 22s. CI needs no pin; it already tracks latest.

The same bump reworded SA1019 from parser.ParseDir to go/parser.ParseDir,
which silently voided the openapigen exclusion, so the pattern now
matches either spelling.

fasthttp Client.RetryIf is deprecated in favour of RetryIfErr. The old
path left resetTimeout at its zero value, so returning false preserves
the existing retry timing exactly.

The rest are gofumpt redundant-paren removals from the stricter
formatter — semantic no-ops.

-Ownership is decided by WHAT YOU WOULD HAVE TO BE RIGHT ABOUT for the finding to
-be true, not by how bad the consequence would be.
-
-| lane | owns |
-| --- | --- |
-| **Senior Developer** | Correctness, edge cases, nil and empty handling, regressions. Layering and the `runtime.Runtime` dispatch rule. Security in code: authn/authz, input validation, injection, XSS, CSRF, SSRF, path traversal, secrets, unsafe defaults — weighted at `internal/web/controller/`, session and middleware, the PUBLIC `internal/sub/` surface, and Xray config generation. Concurrency: races, deadlocks, goroutine and task leaks around the Xray and mtg-multi children, the cron jobs, the eventbus, the websockets. Performance. Maintainability and the 2-line comment cap. Frontend code quality. **Every client-facing field name, encoding and hash choice** the change emits. |
-| **Senior QA** | `internal/database/**`, `internal/database/model/**`, `internal/config/`, `internal/web/translation/**`, `tools/openapigen/`, `frontend/src/pages/api-docs/endpoints.ts`, `.github/workflows/**`, `Dockerfile*`, `docker-compose.yml`, `install.sh`, `x-ui.sh`, `DockerInit.sh`, `Makefile`, `CLAUDE.md`, `frontend/CLAUDE.md`, `docs/**`, `README*`, `SECURITY.md`. Plus intent, upgrade safety, blast radius, backward compatibility of those contracts, operational impact, and labels. |
-| **Senior Tester** | Test quality and coverage, what CI proved and what it did not, weak assertions, vacuous tests, snapshot and golden-fixture abuse. |
-| **Arbiter** | Reconciliation, upstream wire-format resolution, and divergence BETWEEN the three link implementations. |
-
-### Boundaries that are easy to get wrong
-
-- **Field names are the Developer's, never QA's** — a config key, JSON tag, URI
-  parameter, YAML key, TOML key, value encoding, hash choice, or which of two
-  variables a field is populated from. However large the blast radius. If your
-  finding is only true when one of those is wrong, it is the Developer's.
-- **QA outside its own files** may report exactly ONE thing: *a configuration
-  that works on the base branch today behaves differently after this ships, with
-  no operator action* — and only when it can state (a) the concrete existing
-  configuration, (b) what it does today, (c) what it does after. Otherwise drop
-  it; the Developer has it.
-- **Destroying data IS QA's**, even outside its files: regenerating a live key or
-  UUID, overwriting a stored secret, resetting a traffic counter or expiry. That
-  is blast radius, not correctness.
-- **`docs/lib/xray/`**: QA reports the process omission ("it was not updated").
-  The Arbiter reports semantic divergence between the three implementations. The
-  Developer reports whether the one in front of it emits the right thing.
-- **The Tester never** opines on architecture, naming or what the code emits,
-  and never restates a green CI job as a finding.
-
-## Severity — exactly one per finding, plain text, no emoji
-
-| level | means |
-| --- | --- |
-| Critical | security hole, data corruption or loss, crash, privilege escalation, authentication bypass, unrecoverable migration, or a fleet-wide outage path |
-| High | likely production bug, incorrect behaviour on a common path, a breaking API or subscription-format change, a missing migration, a guaranteed CI break, or a significant performance problem |
-| Medium | missing validation, an unhandled edge case, an undeclared behaviour change, documentation or OpenAPI drift, a maintainability problem, or an untested new code path |
-| Low | minor readability, consistency, operational or documentation improvement |
-| Suggestion | optional improvement with no correctness or release impact |
-
-## Confidence — exactly one per finding
-
-High, Medium, or Low. Reserve **High** for something CONFIRMED in the source and
-citable as `file:line`, or observed in real command output. Anything inferred,
-or resting on a detail you could not check, is Medium or Low.
-
-## Verdict — exactly one
-
-`Approve`, `Comment`, or `Request changes`.
-
-## Finding block
-
-Fields on their own lines:
-
-```
-Severity / Confidence / Category
-Location: file:line as plain text, not a Markdown link
-Problem: what is wrong
-Why it matters: the practical runtime, security, operational or upgrade impact
-Recommendation: the preferred fix
-```
-
-The Tester replaces `Why it matters` with `Evidence`: the command or CI job and
-the real output it read. A code example is optional and, if included, must be a
-plain fenced code block — never a ```suggestion``` block, since the Arbiter
-republishes the text.
-
-## Reporting discipline
-
-- Report every problem, including Low and Suggestion. Never drop a finding
-  because you are unsure: report it at `Confidence: Low` and say what would
-  confirm it. Severity and confidence ARE the filter.
-- Dropping a finding because it is not YOURS is different, and is exactly what
-  the lane map asks for. A duplicate only costs the Arbiter a merge.
-- Do not report the same issue twice, do not bikeshed style, and ignore
-  pure-formatting changes unless they reduce readability. Ignore lock files and
-  true vendor code; do NOT ignore test fixtures or generated files.
-- If the diff is too large to cover completely, say so and name the files you
-  did NOT review. A truncated review that does not admit it is worse than none.

+# Review instructions
+
+3x-ui is a Go (Gin + GORM) web panel that generates configuration, share links
+and subscriptions for other programs — Xray-core, mihomo, sing-box, mtg-multi —
+and is deployed by operators who upgrade in place. Judge findings by what
+breaks for those consumers and operators, not by style.
+
+## What a blocking finding means here
+
+Reserve blocking severity for:
+
+- Security on the exposed surfaces: `internal/web/controller/`, session and
+  middleware code, the PUBLIC `internal/sub/` subscription server, and Xray
+  config generation in `internal/xray/`.
+- A state-changing inbound or client operation that bypasses `runtime.Runtime`
+  (`internal/web/runtime/`) and calls `internal/xray/api.go` directly, or
+  dispatches from a controller or cron job. It passes every local test and
+  silently breaks every multi-node deployment.
+- A schema or model change without a matching hand-written migration in
+  `internal/database/db.go`, one that behaves differently on SQLite and
+  PostgreSQL, or one that loses or overwrites operator data on upgrade or
+  rollback. There are no migration files and no down-migrations.
+- A change to what the panel emits on the wire — Xray config JSON, share
+  links, subscription/Clash YAML, mtg-multi TOML — that a downstream client
+  would reject or read differently, or that makes the three independent link
+  implementations (Go `internal/util/link/` + `internal/sub/`, TS
+  `frontend/src/lib/xray/`, TS `docs/lib/xray/`) diverge from one another.
+- Any edit to `.github/workflows/`: this repository runs workflows with
+  secrets against a public fork stream. Untrusted expression interpolation
+  into `run:` blocks, broadened permissions, weakened guards, or a job that
+  executes pull-request code is blocking.
+
+Style, naming and refactoring suggestions are nits at most.
+
+## Always check
+
+- A new `g.POST`/`g.GET` in `internal/web/controller/` needs the whole chain:
+  an entry in `frontend/src/pages/api-docs/endpoints.ts`, regenerated
+  artefacts (`make gen`), any new API-boundary struct added to `StructAllow`
+  in `tools/openapigen/main.go`, and `frontend/public/openapi.json` copied to
+  `docs/public/openapi.json` with the docs MDX regenerated
+  (`cd docs && pnpm gen:api`). CI checks the first three; the docs copy is
+  checked by nothing — a missed copy is blocking, not a nit.
+- A new i18n key exists in ALL 13 locale files in `internal/web/translation/`
+  and is referenced from `frontend/src` or Go in the same PR.
+- A bug fix carries a test that would fail without the fix. A test that
+  passes either way, asserts only `err != nil` or `len(x) > 0`, or was made
+  green by regenerating golden fixtures or Vitest snapshots is a real finding.
+
+## Do not report
+
+- Anything CI already enforces: golangci-lint and gofumpt, oxlint, format
+  and typecheck, `npm audit`, govulncheck.
+- The contents of generated files (`frontend/src/generated/`,
+  `frontend/public/openapi.json`, `docs/public/openapi.json`) or lock files.
+  Those files being STALE after a source change is reportable; their style
+  is not.
+- Missing tests for getters, constants, renames or pure map lookups —
+  `CLAUDE.md` rejects such tests outright.
+
+## Verification bar
+
+- A claim about behaviour needs a `file:line` citation from this repository,
+  not an inference from a name.
+- A claim that a downstream client rejects or requires a wire-format detail —
+  a config key, JSON tag, URI query parameter, YAML or TOML key, an encoding
+  or hash choice — must name the upstream symbol that decides it (repository,
+  file, identifier). If you cannot verify it, keep the finding but say
+  explicitly that it is unverified instead of asserting it.
+
+## Cap the nits
+
+Report at most five nits per review and say "plus N similar" in the summary
+for the rest. Lead the summary with "No blocking issues" when everything found
+is a nit. After the first review of a PR, report blocking findings only.
