gsxdsm 9e4a0817db feat: restart the development engine on source changes (#3329) 
## Summary

Add an opt-in source-development loop that restarts the dashboard and
engine when runtime TypeScript or JSON changes. Use `pnpm dev:watch`;
`pnpm dev:hmr` now combines Vite UI HMR with the same supervised
API/engine restart path.

The watcher filters tests, fixtures, generated declarations, build
output, and task state. It coalesces bursts with a two-second maximum
wait, waits for the child to acknowledge its IPC listener, and rebuilds
runtime dist artifacts before a source-triggered respawn.

## Safety model

- Close scheduler, triage, heartbeat, mission, routine, self-healing,
and merge admission before checking for active work.
- Let already-running agents reach a safe boundary; do not mutate
durable pause settings.
- Enter the existing graceful exit-code-86 shutdown and supervised
respawn path.
- Retry failed liveness reads and declined restart requests instead of
dropping the pending change.
- Keep ordinary `pnpm dev` behavior unchanged; inherited watch state
does not break nested non-dashboard development commands.

A development restart intentionally replaces the dashboard process, so
transient dashboard connections and project dev-server children
reconnect or restart with it. Agent work is the protected boundary.

## Validation

- `pnpm lint`
- `pnpm test:gate` (753 tests passed across engine, core, PostgreSQL
gate, and CI-shape suites)
- Focused CLI watcher/restart/supervision suites: 40 tests passed
- Focused engine drain/manager suites: 52 tests passed
- `pnpm --filter @runfusion/fusion typecheck`
- `pnpm --filter @fusion/engine typecheck`
- `pnpm verify:fast` (13 steps passed, including CLI build and real
health boot smoke)
- Manual unsupported-command probe confirms explicit `--watch` fails
clearly outside the dashboard command

## Post-Deploy Monitoring & Validation

- Watch for `[fusion:dev] source changed`, `source restart deferred`,
`active work drained`, and `restart requested` logs during the first
watched development session.
- Healthy behavior is one exit-86 respawn per edit batch, no interrupted
active agents, refreshed dist artifacts, and a healthy dashboard after
respawn.
- Investigate repeated restart loops, watcher attachment warnings,
declined restart retries, or liveness-read failures.
- Immediate mitigation is to use ordinary `pnpm dev` without `--watch`;
no production runtime behavior or durable setting needs rollback.
- Validation owner: Fusion maintainers during the first source edit
after merge.

## Summary by CodeRabbit

* **New Features**
* Added `pnpm dev:watch` to automatically restart development runtime
processes when source files change.
* Development restarts now wait for active work to finish, preventing
new work from starting during the transition.
* Enhanced `pnpm dev:hmr` with graceful runtime source restarts while
keeping the dashboard available.
  * Rapid source changes are grouped to avoid unnecessary restarts.

* **Documentation**
* Updated development setup and contribution guides with the new watch
workflow.
