Agents that use `git worktree add` to run parallel branches end up with one
indexed project per worktree. Each is a near-duplicate of the main checkout,
so the cache fills with redundant graphs and project pickers get noisy.
Add an opt-in `ignore_worktrees` config key. When enabled, a linked worktree
is left alone:
- auto-index on connect skips it (logged as autoindex.skip)
- the daemon's background auto-index skips it
- explicit index_repository refuses with an actionable message naming both
ways forward (index_worktree=true, or turn the key off)
- the hook-augment "not indexed" guidance stops telling the agent to run
index_repository in a directory where it would only be refused
Detection is git plumbing, no subprocess: <path>/.git must be a regular file
holding a "gitdir:" pointer AND that gitdir must contain a `commondir` file.
The commondir check is what separates a linked worktree from a submodule,
whose .git is also a gitlink file but whose gitdir has no commondir. The main
checkout of a repo that has worktrees is never affected.
Defaults to false, so behaviour is unchanged unless the key is set.
