What does this PR do?

Fixes #2733. With auto_watch=true, a successful index_repository request from an initialized MCP session now registers the requested project and root for automatic refresh. A client started in a workspace can index a custom-named worktree and keep it fresh while that client remains connected. Previously that target reported watched: false with reason: not_session_project after a successful index.

Track each session's memberships separately from physical watches. Shared projects remain watched until their last owner disconnects. Async completion registers a target only while a requesting session is connected; failed jobs and one-shot CLI requests do not add watches. Preserve the indexed mode and persistence option for watcher refreshes, and remove secondary watches when global auto_watch is disabled.

This uses the existing configuration and tool arguments and retains workspace-root and tool-profile checks. Update the runtime instructions, status hint, README, and configuration reference accordingly. Related: #1429, #1660.

Validation

• Passed scripts/lint.sh --ci with Cppcheck 2.20.0, make -f Makefile.cbm lint-tidy-diff, scripts/security-audit.sh, and git diff --check.
• Passed the embedded-UI production build, tests/test_watcher_disabled.sh, and tests/test_worker_session_scope.sh against the resulting binary.
• Passed scripts/test.sh --suites daemon_application,sqlite_writer,mcp CC=clang CXX=clang++: 476 passed, 4 skipped. Passed ASAN_OPTIONS=detect_leaks=0:detect_stack_use_after_return=0 make -f Makefile.cbm test CC=clang CXX=clang++: 9,905 passed, 9 skipped, exit 0.
• scripts/test.sh stops at Step 0w: the published language-count check lists five surfaces with no remaining count claim (docs/index.html, docs/llms.txt, pkg/npm/README.md, scripts/package-release.sh, server.json). These files and the checker are unchanged from the base commit 4cf44147. This remains a draft while the full entry point is failing.

Local sanitizer builds retain two pre-existing ObjectScript scanner zero-length memcpy guards; those changes are outside this PR. ASan/UBSan test runs disable LeakSanitizer because of the local ptrace environment.

AI assistance: OpenAI Codex assisted with implementation, regression tests, documentation, and review. The submitting contributor is responsible for this change.

Checklist

• Every commit is signed off (git commit -s)
• Tests pass locally (make -f Makefile.cbm test)
• Lint passes (make -f Makefile.cbm lint-ci)
• New behavior is covered by tests (the original failure was also observed through MCP)

[github-actions]

Thanks for opening this — it has been seen, and it is queued.

This note is automated, but it is not a brush-off: it exists so you know where your PR stands instead of having to guess from silence.

Current review status: working through a backlog. 0.9.1-rc.1 is out, so the release freeze that held reviews is over — but it left a large queue of open pull requests behind it, and we are reading through them oldest-first. The background is in discussion #1144.

What that means for this PR, concretely:

• It will not be closed for inactivity. No stale bot touches pull requests here.
• It may still sit a while before a human reads it. That is on us, not on you.
• Older PRs are read first, so a recent one is not being skipped — it is behind a queue.

Things that will genuinely speed it up whenever review does happen:

• Keep it rebased on main — the tree is moving quickly right now, and a conflicting branch cannot be reviewed as the diff you intended.
• Get CI green, or say which failures you believe are pre-existing.
• Keep the change to one claim. Bundled features and refactors get split before they get merged, which costs you a round trip.
• Every commit needs a sign-off (git commit -s) — CI enforces DCO.

If this fixes a bug, a reproduction we can run is worth more than a description of the symptom.

Thanks for contributing, and sorry in advance for the wait.
