Fixes#4046
## Problem
When a single run creates more than 1000 idempotency keys (e.g. a large
batch trigger where each item calls `idempotencyKeys.create()`), the
original key and scope metadata is silently dropped for all but the most
recent 1000 keys.
`idempotencyKeys.create()` returns a plain 64-char hash and stores the
`{ key, scope }` mapping in an in-process catalog keyed by that hash.
That catalog was a fixed-size **LRU capped at 1000 entries**. Once a run
creates more than 1000 keys, the earliest mappings are evicted, so when
the SDK later looks them up to attach `idempotencyKeyOptions` to the
trigger call, it finds nothing and sends `undefined`. The affected runs
then:
- report `ctx.run.idempotencyKey` as the raw hash instead of the
user-provided key
- have no `idempotencyKeyScope`
- show empty `idempotency_key` / `idempotency_key_scope` in the
dashboard and analytics
Deduplication still works (the hash is intact); only the human-readable
metadata is lost, which makes the failure silent and hard to notice.
## Fix
- Replace the LRU catalog with an unbounded in-memory catalog, so every
key created within a run keeps its metadata regardless of how many are
created.
- Clear the catalog at each run boundary via
`resetExecutionEnvironment()` (both dev and managed workers), matching
how every other per-run manager is reset. Deployed workers reuse one
process across many runs (warm starts), so this bounds memory to a
single run's keys instead of accumulating across runs — which is the
reason the size cap existed in the first place.
## Tests
- New public-API test creates 3000 keys and asserts all of them
(including the first) retain their key/scope — this fails on `main` and
passes with the fix.
- New test for the in-memory catalog covers store/retrieve/overwrite,
large-N retention (no eviction), and `clear()`.
- New test asserts the catalog is emptied after a run-boundary reset.
- Replaces the previous LRU catalog + its eviction tests.
Verified: `@trigger.dev/core` and `trigger.dev` both build; all
idempotency tests pass. Changeset added (patch).
