In --watch-web dev mode the server silently fell back to the embedded SPA
snapshot whenever the disk dist/ was missing or partial, so edits to the
web app appeared not to take effect with no error anywhere. This change
makes the dev loop visible and quick:
- static_files plumbs a dev_disk_only flag from RouterOptions.watch_web
into the fallback handler. When set, embedded fallback is skipped and
a miss returns 503 with a "build in progress" auto-refresh page.
- The web build script writes each rebuild into apps/fabro-web/.dist-builds/<id>/
and atomically replaces the dist symlink via rename(2), so requests
never observe a partially-populated dist tree.
- Tailwind is invoked through node_modules/.bin/tailwindcss directly
instead of bunx, removing a per-rebuild bun add @latest --force round-
trip and dropping rebuild time from ~10s to ~250ms.
- load_asset no longer falls through to the workspace dist/ when an
explicit asset_root is provided, restoring test isolation when a
real dev build is sitting next door.

Always route non-empty Files Changed views through Pierre's Virtualizer and worker pool, with full-height layout propagation and stable per-file cache keys. Copy Pierre worker assets during the web build so the static worker URL resolves in production.
Keep project config and checked-in workflows under .fabro so they stay out of
normal repo listings. Update config discovery, CLI project commands, fixtures,
docs, and checked-in workflow paths to use .fabro/project.toml and
.fabro/workflows/*.
Replace the unsupported Bun.watch call in the SPA build script with
node:fs.watch so `bun run dev` keeps running in local development.
Add a regression test that verifies watch mode stays alive until
interrupted.
