🔁 fix: Pass recursionLimit to OpenAI-Compatible Agents API Endpoint (#12510)
* fix: pass recursionLimit to processStream in OpenAI-compatible agents API

The OpenAI-compatible endpoint never passed recursionLimit to LangGraph's
processStream(), silently capping all API-based agent calls at the default
25 steps. Mirror the 3-step cascade already used by the UI path (client.js):
yaml config default → per-agent DB override → max cap.

* refactor: extract resolveRecursionLimit into shared utility

Extract the 3-step recursion limit cascade into a shared
resolveRecursionLimit() function in @librechat/api. Both openai.js and
client.js now call this single source of truth.

Also fixes falsy-guard edge cases where recursion_limit=0 or
maxRecursionLimit=0 would silently misbehave, by using explicit
typeof + positive checks.

Includes unit tests covering all cascade branches and edge cases.

* refactor: use resolveRecursionLimit in openai.js and client.js

Replace duplicated cascade logic in both controllers with the shared
resolveRecursionLimit() utility from @librechat/api.

In openai.js: hoist agentsEConfig to avoid double property walk,
remove displaced comment, add integration test assertions.

In client.js: remove inline cascade that was overriding config
after initial assignment.

* fix: hoist processStream mock for test accessibility

The processStream mock was created inline inside mockResolvedValue,
making it inaccessible via createRun.mock.results (which returns
the Promise, not the resolved value). Hoist it to a module-level
variable so tests can assert on it directly.

* test: improve test isolation and boundary coverage

Use mockReturnValueOnce instead of mockReturnValue to prevent mock
leaking across test boundaries. Add boundary tests for downward
agent override and exact-match maxRecursionLimit.
