Yichen Jiang 0b42259b82 Merge origin/master into worktree/web-plugin-config
Resolves the vendored-package rescope (cordis -> @deepseek-ai/cordis,
schemastery -> @deepseek-ai/schemastery) against this branch's settings
namespaces: the bash capability namespace, its two executors' section
installs, and the new plugin-config client package all move to the scoped
specifiers.

* registering it twice, and a settings document carried between platforms

* implementation per context; loading a second throws, which is cordis'
* standard duplicate-service behavior).
*
* Implementations must honor these semantics:
* - {@link run} rejects only for infrastructure failures. Nonzero exits,
* timeout kills, and abort kills resolve with a {@link BashRunResult}.
* - {@link start} returns immediately; no timeout applies to background
* processes. `done` settles at process close and never rejects; spawn
* failures settle as `killed` with the error on stderr.
* - {@link BashProcess.readOutput} is incremental: consecutive reads never
* repeat output. Lossy reads report truncation and available spill files.
* - A still-running background process is stopped and awaited when its
* owning composition tears down. With the subprocess seam that
* boundary is `ctx.subprocess` disposal, so a background process survives
* an executor-only reload.
