Introduce a primaryWorktree Effect that queries Git plumbing commands
to locate the main checkout from any linked worktree. Integrate it
into config loading so .kilo directory settings from the primary
checkout act as local-scoped fallbacks beneath the active worktree
and KILO_CONFIG_DIR overrides.
Wire primaryPaths into skill discovery so project skills installed in
the primary checkout appear as fallbacks unless overridden locally.
Refactor session family matching to consider sandbox directories and
filter out nested Git repositories when resolving worktree roots.
Convert baselineDirectory in indexing to an Effect that delegates to
primaryWorktree instead of reading Instance.project.worktree directly.
Restore the content() signal usage in the TUI text part renderer.
Provide Git.defaultLayer across all affected test layers and add
coverage for linked worktrees, submodules, paths with spaces, sandbox
project matching, and primary config directory precedence.
