feat(mcp): map gitea_commit_files in task capability resolver (closes #262)

gitea_get_runtime_context now reports per-task allowed_in_current_session
flags, matching configured profiles, and aggregate session_capabilities so
LLMs can determine author/comment/review/merge ability without guessing
launcher profile config.

+## Work Selection Rule for LLMs
+
+Before starting any issue or PR work, acquire or verify a work lease. Do not
+begin coding, reviewing, fixing, branching, committing, pushing, commenting,
+or creating a PR until you prove the target is not already being worked.
+
+Required checks:
+
+1. List open PRs.
+2. Search for PRs linked to the target issue.
+3. Search local and remote branches for the issue number.
+4. Search registered worktrees for the issue branch.
+5. Check dirty worktrees.
+6. Check active leases or recent handoffs.
+7. Check whether the issue was already completed by a merged PR.
+
+If another active LLM/session owns the lease, stop. Allowed responses:
+continue as the lease owner; review the existing PR if reviewer capability
+allows; produce a handoff; request takeover after lease expiry; stop with
+"work already claimed."
+
+Never create a parallel branch or PR for the same issue unless the old branch
+is proven abandoned and the takeover is recorded.
+
+Gitea-Tools lease gates: `gitea_lock_issue` (fail-closed before author
+mutations), `status:in-progress`, and claim comments. Full portable wording:
+[`skills/llm-project-workflow/SKILL.md`](../skills/llm-project-workflow/SKILL.md).
+
+## Global LLM Worktree Rule
+
+The main project checkout is a stable control checkout. It must stay on the
+configured stable branch: `master`, `main`, or `dev`.
+
+All LLM task work must happen inside the project's `branches/` directory.
+
+Before any mutation, prove:
+
+1. current project root
+2. current working directory
+3. current branch
+4. stable branch for the main checkout
+5. session-owned worktree path under `branches/`
+
+If `cwd` is not inside `branches/`, stop. Do not edit, create, delete, format,
+test-write, commit, merge, rebase, checkout task branches, resolve conflicts,
+or run cleanup.
+
+There are no exceptions for small fixes, docs, tests, cleanup, PR review fixes,
+conflict resolution, or emergencies.
+
+The main checkout may only be used for read-only inspection, fetching,
+stable-branch update after merged PRs, creating `branches/` worktrees, or
+explicit control-checkout repair.
+
+Portable wording: [`skills/llm-project-workflow/SKILL.md`](../skills/llm-project-workflow/SKILL.md).

   owner decision.** Do not create a new repository or a new tracker unless
   explicitly approved by the owner.
 
+## Work Selection Rule for LLMs
+
+Before starting any issue or PR work, acquire or verify a work lease.
+
+Do not begin coding, reviewing, fixing, branching, committing, pushing,
+commenting, or creating a PR until you prove the target is not already being
+worked.
+
+Required checks:
+
+1. List open PRs.
+2. Search for PRs linked to the target issue.
+3. Search local and remote branches for the issue number.
+4. Search registered worktrees for the issue branch.
+5. Check dirty worktrees.
+6. Check active leases or recent handoffs.
+7. Check whether the issue was already completed by a merged PR.
+
+If another active LLM/session owns the lease, stop.
+
+Allowed responses:
+
+- continue as the lease owner,
+- review the existing PR if reviewer capability allows,
+- produce a handoff,
+- request takeover after lease expiry,
+- stop with "work already claimed."
+
+Never create a parallel branch or PR for the same issue unless the old branch
+is proven abandoned and the takeover is recorded.
+
+For Gitea-Tools: `gitea_lock_issue` is the fail-closed lease gate before author
+mutations; `status:in-progress` and claim comments are supporting lease signals.
+Use `review_proofs.classify_issue_for_selection` when reporting fresh issue
+selection (#188).
+
+## Global LLM Worktree Rule
+
+The main project checkout is a stable control checkout. It must stay on the
+configured stable branch: `master`, `main`, or `dev`.
+
