feat: add session end lifecycle callback

[chenghao-mou]

Behavior: Add onSessionEnd after the primary session closes and before internal report generation. Bound the callback to 300 seconds, then flush final OTEL logs after shutdown callbacks.

Parity: Apply Python's 30-second connect and 900-second total deadlines to session report uploads. Retry only connection setup failures or responses with RetryInfo.

Validation: Agents tests, build, typecheck, lint, format, and throws checks pass. The API check still reports unrelated baseline drift.

Addresses AGT-3407
Addresses #2375

Initial prompt and agent context

Model: GPT-5.6

can you review the issue from #2375

okay, we should port over the relevant changes

session report should inherit the 30/900 timeout values, right?

okay, can you add them in the port as well?

okay, create a PR.

🟥 Room names bypass telemetry redaction

Session reports export room names under unmarked room. PII-enabled collectors cannot strip these customer-controlled names.

(Refers to this code)
