Save-as-plan and Add-to-notes actions were disabled on messages whose session
ran in a worktree, because session.directory alone does not reflect the
worktree attachment — the authoritative cwd lives in session-worktree-store.
Use useEffectiveDirectory (attachment cwd > worktree metadata > session.directory)
and resolve the parent project via the worktree map the sidebar already builds,
extracted into lib/projectResolution so session-ui-store and chat actions share
one resolver. No extra git calls.
