kshitijk4poor f4fbaa6cda fix(langfuse): bound _TRACE_STATE growth from non-finalizing turns ... Scoping the trace key by turn_id (the prior commit) fixed cross-turn collisions but introduced a slow leak: _finish_trace only pops a key when a turn ends cleanly (final response has content and no tool calls), so any turn that is interrupted, ends on a tool call, or has empty final content now leaves its uniquely-keyed entry in _TRACE_STATE forever. Previously the constant per-session key was overwritten by the next turn, capping growth at ~1 entry per session. Add an LRU cap (_MAX_TRACE_STATE) enforced by _evict_stale_locked, called under _STATE_LOCK immediately before each insert. It evicts the least-recently-updated entries (using the previously-dead last_updated_at field) and ends their root span so nothing dangles. Regression test drives 50 non-finalizing turns against a cap of 8 and asserts the dict stays bounded with the most-recent turns surviving.		2026-06-18 12:59:41 +05:30
