…d skills

The server reports the checkout containing each project (found by walking
to the nearest .git, so it works without a remote) as an optional, unsaved
repositoryRoot on project shells. The agent's cwd and the web and mobile
composers (skills, path search, reply links) place a subdirectory project
inside the thread's worktree with one shared helper. Git, checkpoints, and
terminals stay at the checkout root.

… agree on mention paths

- Provider switch plans compare against the RuntimePolicy cwd, so a same-instance
  model switch in a subdirectory worktree no longer restarts the session.
- Composer mentions are relative to the file panel's root, or absolute when the
  agent works in a subdirectory of it; picker and tree now name the same file and
  saved checkout-relative mentions still open.
- Mobile reply links like ../shared/x resolve from the agent's cwd within the
  checkout.
- The agent-cwd directory check is refreshed on branch changes and finished runs.
- A failed repository identity lookup no longer drops the checkout root.

…open sessions when the agent cwd moves

- Saved and queued mentions are checkout-relative; when the agent runs in a
  subdirectory of the worktree, the provider now gets them joined to the
  checkout instead of reading them against its own cwd.
- An idle provider session whose cwd no longer matches the runtime policy
  (a branch gained or dropped the project subdirectory) is released and
  reopened at the new cwd. Busy sessions, sessions shared with other threads,
  and sessions with pending background work are kept.
- Composer mention chips resolve icons and tooltips from the file panel's root.

Home-relative mention paths such as ~/.agents/AGENTS.md are no longer
joined onto the checkout for a subdirectory agent cwd. The cwd-change
session reopen is removed: adapters that report a canonicalized cwd
never matched it, so idle sessions were reopened on every turn.

Tapping a saved mention joined every non-absolute path onto the file
route root, so ~/.agents/AGENTS.md opened <checkout>/~/.agents/AGENTS.md.
Home-relative mention paths now pass through unchanged, as on main.
