Tilt live_update adds initial_sync for pre-built images

For a pre-built image, add `initial_sync()` first in `live_update` to upload files from its `sync` paths when Tilt first observes a running container and after restarts. Then define `sync` steps and optional `run` triggers; during initial sync, untriggered `run` steps execute and triggered ones execute only when synced files match.

live_update=[ initial_sync(), sync('./src', '/app/src'), run('npm install', trigger=['./src/package.json']), ]

tilt alpha tree-view displays dependency resources

When you need to find resources blocking readiness, run `tilt alpha tree-view --blockers` to show blocked resources and their root blockers. The tree is organized by dependencies from the root Tiltfile; use `--dedupe` to show repeated subtrees only once.
