Move session init to session_start and after_compaction hooks

Browse Source 
Init was incorrectly placed in before_agent_start, which fires on every
agent attempt (retries, context overflow, auth rotation). Session init
should fire once on /new or /reset (session_start) and after compaction
(after_compaction). before_agent_start now only syncs MEMORY.md and
tracks workspace dirs.
