Auto-generated display titles (LLM or derived) were passed to Honcho's
resolve_session_name() as authoritative, so a titled per-repo,
per-directory, or global session silently remapped onto a second Honcho
session named after the generated title. Only explicit /title commands
(user provenance) should act as an intentional session-name override.
Thread session_title_source from the session DB through
agent_init into the Honcho provider, and skip title-based remapping
when the source is 'derived' or 'llm'. Missing provenance keeps the
legacy explicit-title behavior for callers that predate source
threading. Gateway per-chat keys and per-session identity safeguards
are unchanged.
Adds regressions for titled per-repo, per-directory, and global
sessions at both the resolver and provider level.
