fix(agent): remove hardcoded 30s timeout in title_generator

[Elagizy]

Problem

The generate_title() function in agent/title_generator.py hardcoded timeout=30.0, bypassing the configured auxiliary LLM timeout from config.yaml. This caused title generation to fail when using slow local models with cold start times exceeding 30 seconds (e.g., qwen3.6-27b at ~88s cold start).

Solution

Changed default to timeout=None so it falls through to the configured value, allowing users to tune the timeout for their model response time characteristics.

Changes

• agent/title_generator.py: Changed timeout: float = 30.0 → timeout: float = None
• Updated docstring to explain the behavior

[alt-glitch]

Likely duplicate of #18129 — same root cause: hardcoded 30s timeout in title_generator.py insufficient for slow local models. Previous attempt #18838 was already closed as duplicate.

Likely duplicate of #18129 — same fix for hardcoded 30s timeout in title_generator.py.

Thanks for the focused configuration-correctness fix. Closing as implemented on main; this is an automated hermes-sweeper review.

• 5126902f1d77ccca0fb7b0f9c780d9b80e6a4fe2 (fix(title): honor configured auxiliary timeout) already changed agent/title_generator.py:54 to default timeout to None and forwards it at agent/title_generator.py:87.
• agent/auxiliary_client.py:6054-6065 resolves a None timeout from auxiliary.{task}.timeout, so auxiliary.title_generation.timeout now controls this path.
• tests/agent/test_title_generator.py:62-91 covers both config delegation and explicit-timeout override behavior.
• This supersedes the duplicate-family discussion referencing fix(agent): make title generation timeout configurable via auxiliary.title_generation.timeout #18129.
