chore(webapp,core): remove the end-of-life v3 (engine V1) execution stack (#4236)
## Summary v3 (the engine that ran the SDK v3 era, internally `RunEngineVersion.V1`) is end-of-life. Following the removal of the v3 execution apps ([#4194](https://github.com/triggerdotdev/trigger.dev/pull/4194)) and the legacy dev websocket ([#4198](https://github.com/triggerdotdev/trigger.dev/pull/4198)), this removes the remaining v3 execution stack from the server. Clients still on v3 (an old SDK or CLI that has not upgraded) keep getting a clear "upgrade to v4" response. Triggers, batch triggers, reschedules, and deploys that resolve to v3 are rejected with a graceful 4xx pointing at the migration guide, never a 5xx, so a stale client cannot affect server health. Self-hosted instances still running v3 should stay on the 4.5.x release line until they migrate. ## What is removed - The MarQS queue and its shared/dev queue consumers. - The v3 socket.io namespaces (coordinator, provider, shared-queue) and the v3 run lifecycle services (attempt, checkpoint, and batch-resume). - The graphile-worker background job system; all live jobs already run on `@trigger.dev/redis-worker`. - The `DEPRECATE_V3_ENABLED` flag: v3 is now rejected unconditionally, so the flag is gone. - Unused v3 exports from `@trigger.dev/core` (the `v3/zodNamespace` subpath and the legacy socket message catalogs) and the now-dead MarQS environment variables. ## What stays The v4 engine is untouched. The graceful v3 rejection boundary stays, `determineEngineVersion` still detects a v3 project so it can reject it, and the batch service plus batch-completion worker stay for current clients. Live queue concurrency limits and metrics now read from the v4 run engine instead of MarQS, and a brand-new dev environment now defaults to v4. ## Dependency cleanup Removes webapp dependencies left unused by this change: `seedrandom` and `semver` (only the removed v3 code used them) plus a set that was already dead, their orphaned `@types` packages, and two dead files. Adds a `knip:deps` script and a `knip.json` config so unused dependencies can be found the same way going forward.

- **Deploy fails with `ERROR: schema "graphile_worker" does not exist`.** This error occurs when Graphile Worker migrations fail to run during webapp startup. Check the webapp logs for certificate-related errors like `self-signed certificate in certificate chain`. This is often caused by PostgreSQL SSL certificate issues when using an external PostgreSQL instance with SSL enabled. Ensure that both the webapp and supervisor containers have access to the same CA certificate used by your PostgreSQL instance. You can configure this by mounting the certificate file and setting the `NODE_EXTRA_CA_CERTS` environment variable to point to the certificate path. Once the certificate issue is resolved, the migrations will complete and create the required `graphile_worker` schema.
