Before: dev-server watched packages/daemon/src + dev scripts + package.json.
SF extension source edits in src/resources/extensions/sf/ AND coding-agent
edits in packages/coding-agent/src/ did NOT trigger restart. Operators had to
restart manually after copy-resources / git pull / coding-agent edits.
Adds three watched paths:
1. packages/coding-agent/src — rpc-mode hosts sf_feedback / start_autonomous
handlers, lives here. Edits must restart the sf child.
2. dist/resources/.sf-resource-build-stamp — atomic stamp updated by
copy-resources. Watching the stamp (not the dist tree) avoids heavy
recursive walk while picking up extension upgrades the moment they land.
Idempotent: ensure-source-resources only updates the stamp when an actual
rebuild ran, so no restart-loop on identical re-runs.
3. .git/HEAD — changes on pull / branch switch / commit. Catches upgrade
flows where source moved outside this process.
Native (packages/native/) intentionally not watched — Rust build is 5–10 min,
auto-trigger would loop. Operator triggers native rebuild manually per the
existing ensure-source-resources policy.
