Subject: [PATCH] fix(mcp): pin langbot-plugin 0.4.10 - per-process memory_mb
 for node OOM fix (#2314)

* fix(mcp): bump default memory to 1024MB for node (npx) stdio MCP servers

Node.js MCP servers (npx/bunx) were being OOM-killed (return_code=137) by the
default 512MB nsjail cgroup_mem_max. Node V8 reserves large virtual address
space and instantiates WebAssembly modules (undici llhttp) on startup, easily
exceeding 512MB resident. This caused every node-based MCP (memory,
sequential-thinking, filesystem, weather, docker, excel) to crash-loop.

Fix: when the stdio command is npx/bunx/pnpm, default memory_mb to 1024 unless
the operator explicitly set a value. Python/uvx servers keep the 512MB default.

* chore(deps): pin langbot-plugin 0.4.10 (per-process memory_mb fix)

* chore: update uv.lock for langbot-plugin 0.4.10
