Matt Aitken f4a96bdf84 Fail dev and deploy on duplicate task ids (#3865)
## What

`dev` and `deploy` now fail with a clear error when two tasks are
defined with the same id — including across task types (e.g. a scheduled
task and a regular task sharing an id).

## Why

Tasks are registered into the resource catalog keyed by id, so a second
definition with the same id silently overwrote the first. One of the
tasks would just vanish from the worker with no warning — easy to miss,
hard to debug. (Any earlier duplicate-id check ran against the
post-registration task list, which is already de-duplicated, so it never
actually fired.)

## How

- **Detect at registration** (`@trigger.dev/core`):
`StandardResourceCatalog` records a collision when a task id is
registered more than once, capturing the files involved — the only point
where both definitions are visible before the id-keyed map collapses
them. Exposed via `listTaskIdCollisions()`.
- **Fail indexing** (`trigger.dev` CLI): both index workers report
collisions via a new `TASKS_FAILED_TO_INDEX` message;
`indexWorkerManifest` rejects with a new `DuplicateTaskIdsError`. `dev`
renders a dedicated error (offending ids + files + docs link); `deploy`
fails with the same message. Runtime worker boot is unaffected — it
never reads the collisions.
- **Server-side backstop** (webapp): background-worker registration also
rejects duplicate ids with a clear `ServiceValidationError`, so
duplicates are caught even from an older CLI.

## Testing

- Unit tests for collision collection in the catalog and for the
error-message formatting (standard, same-file, and 3+-definition cases).
- Verified end to end against a local webapp: a project with a regular
task and a scheduled task sharing an id now fails `dev` with the
dedicated error; a project with distinct ids still starts normally.

## Changeset

Patch for `@trigger.dev/core` and `trigger.dev`.
