Keep HMR working when the dev server runs from a worktree

[RBilly]

Why

Running bun run dev (or tauri:dev) from inside a Maestro-created worktree gave no HMR at all — every edit required a manual reload.

The cause is the watcher ignore list. **/.maestro/** is matched by substring against the absolute path chokidar reports, and a worktree lives at <repo>/.maestro/worktrees/<name>/. So for a dev server started there, every file it watches contains .maestro/ and the entire checkout was ignored.

What

Match the path relative to this config file instead of using a floating glob:

ignored: (file) =>
  ["src-tauri", ".maestro"].includes(path.relative(projectRoot, file).split(path.sep)[0]),

A worktree now watches its own sources, and still ignores its own nested .maestro/ and src-tauri/ — so the original reason for the entry (a worktree checkout's index.html/tsconfig.json making Vite hard-reload the app mid-worktree-creation) still holds. Vite 8 accepts a function for server.watch.ignored (AnymatchMatcher), so this needs no new dependency.

Verified in a worktree dev server: editing src/App.tsx logs hmr update /src/App.tsx, while creating a file under .maestro/worktrees/ triggers nothing.

Also trims the comments in vite.config.ts — the Tauri template's numbered list and the vite.dev/config link are gone, and each remaining comment is 1-3 lines carrying only the non-obvious reason.
