fix(session): pass ctx/user/session_id into async commit memory extraction

[mvanhorn]

Summary

Session.commit_async() calls extract_long_term_memories() without passing user, session_id, or ctx. Because the compressor returns early when ctx is None, async session commits always produce memories_extracted = 0 even when the archived messages contain extractable memories.

Why this matters

• #602 documents the regression with reproduction steps and commit evidence
• The sync commit() path correctly passes all three parameters (session.py:263-267)
• The async path lost them after the COW pattern revert (#584)
• This breaks memory extraction for integrations using the async commit endpoint (OpenClaw / memory-openviking)

Changes

openviking/session/session.py line 338: Added the three missing keyword arguments to match the sync path:

# Before (broken):
memories = await self._session_compressor.extract_long_term_memories(
    messages=messages_to_archive,
)

# After (fixed):
memories = await self._session_compressor.extract_long_term_memories(
    messages=messages_to_archive,
    user=self.user,
    session_id=self.session_id,
    ctx=self.ctx,
)

Testing

• Verified the sync path (line 263) passes user, session_id, ctx
• Verified the compressor guard (if not ctx: return []) at compressor.py:134 is the root cause
• ruff format --check and ruff check pass
