fix(harness)!: hydrate runs from RunStore and persist interrupted status (#2932)
* fix(harness): hydrate run history from RunStore and persist cancellation status

fix:
- Make RunManager.get() async and hydrate from RunStore when in-memory record is missing
- Merge store rows into list_by_thread() with in-memory precedence for active runs
- Persist interrupted status to RunStore in cancel() and create_or_reject(interrupt|rollback)
- Extract _persist_status() to reuse the best-effort store update pattern
- Await run_mgr.get() in all gateway endpoints
- Return 409 with distinct message for store-only runs not active on current worker

Closes #2812, Closes #2813

* fix(harness): consistent sort and guarded hydration in RunManager

fix:
- list_by_thread() now sorts by created_at desc (newest first) even when
  no RunStore is configured, matching the store-backed code path
- guard _record_from_store() call sites in get() and list_by_thread()
  with best-effort error handling so a single malformed store row cannot
  turn read paths into 500s

test:
- update test_list_by_thread assertion to expect newest-first order
- seed MemoryRunStore via public put() API instead of writing to _runs

* fix(harness): guard store-only runs from streaming and fix get() TOCTOU

Add RunRecord.store_only flag set by _record_from_store so callers can
distinguish hydrated history from live in-memory runs.  join_run and
stream_existing_run (action=None) now return 409 instead of hanging
forever on an empty MemoryStreamBridge channel.

Re-check _runs under lock after the store await in RunManager.get() so a
concurrent create() that lands between the two checks returns the
authoritative in-memory record rather than a stale store-hydrated copy.

* fix(harness): reorder bridge fetch in join_run and make list_by_thread limit explicit

Move get_stream_bridge() after the store_only guard in join_run so a
missing bridge cannot produce 503 for historical runs before the 409
guard fires.

Add limit parameter to RunManager.list_by_thread (default 100, matching
the store's page size) and pass it explicitly to the store call.
Update docstring to document the limit instead of claiming all runs are
returned.

* fix(harness): cap list_by_thread result to limit after merge

Apply [:limit] to all return paths in list_by_thread so the method
consistently returns at most limit records regardless of how many
in-memory runs exist, making the limit parameter a true upper bound
on the response size rather than just a store-query hint.

* fix(runtime): add update_model_name to RunStore to prevent SQL integrity errors

RunManager.update_model_name() was calling _persist_to_store() which uses
RunStore.put(), but RunRepository.put() is insert-only. This caused integrity
errors when updating model_name for existing runs in SQL-backed stores.

fix:
- Add abstract update_model_name method to RunStore base class
- Implement update_model_name in MemoryRunStore
- Implement update_model_name in RunRepository with proper normalization
- Add _persist_model_name helper in RunManager
- Update RunManager.update_model_name to use the new method

test:
- Add tests for update_model_name functionality
- Add integration tests for RunManager with SQL-backed store

* fix(runtime): handle NULL status/on_disconnect in _record_from_store

`dict.get(key, default)` only uses the default when the key is absent,
so a SQL row with an explicit NULL status would pass `None` to
`RunStatus(None)` and raise, breaking hydration for otherwise valid rows.
Switch to `row.get(...) or fallback` so both missing and NULL values
get a safe default. Add tests for get() and list_by_thread() with a
NULL status row to prevent regression.

* fix(runs): address PR review feedback on store consistency changes

- Fix list_by_thread limit semantics: pass store_limit = max(0, limit - len(memory_records)) to store so newer store records are not crowded out by in-memory records
- Remove dead code: cancelled guard after raise is always True, simplify to if wait and record.task
- Document _record_from_store NULL fallback policy (status→pending, on_disconnect→cancel) in docstring
