feat: bash-backed glob/grep discovery tools (dsh-tool-fs-search)

Implements docs/rfc/implemented/feature/2026-07-09-bash-backed-grep-glob-
discovery.md: model-facing glob/grep in a new @deepseek-ai/dsh-tool-fs-search
package, executing fixed ripgrep templates through ctx.bash.resolve/run —
not ctx.fs provider methods — so filesystem backends stay free of a search
contract and sandboxed/remote executors substitute cleanly. The tools never
call ctx.bash.start(); the tool layer owns quoting (one singleQuote safety
boundary), rg --json parsing, ItemRetainer/TextRetainer retention, and the
first tool-owned ctx.spillFiles.saveText() handoff (item-level retention the
generic post-execute spill policy cannot recover).

RFC amendments on the way to implemented/: a shared src/search-core.ts (the
SEARCH_* vocabulary + bash-run/raw-spill/spill plumbing was byte-identical
across both tools — the missed-extraction smell), and a snapshot-gap note:
wiring the acp-agent tree changes the assembled prompt, so goldens need a
keyed re-record; the spill notice text is pinned by unit tests instead and
only the coding-agent example ships the tools for now.

/**
* Integration tests: the REAL local bash executor (`dsh-bash-local`) plus a
* REAL ripgrep binary, exercised through `ctx.tools.execute()`. These verify
* the WORLD — actual files on disk are discovered and grepped, hostile
* patterns stay inert in a real shell, and real `rg` stderr classifies into
* the `SEARCH_*` vocabulary. The whole suite self-skips when `rg` is not on
* PATH (a CI accommodation mirroring the keyless e2e skip); the fake-executor
* suite (tools.spec.ts) carries the coverage gate.
