fix(session): Semantic renaming and memory session ID capture for resume

This commit fixes the session ID confusion identified in PR #475:

PROBLEM:
- Using contentSessionId (user's Claude Code session) for SDK resume was wrong
- Memory agent conversation should persist across the entire user session
- Each SDK call was starting fresh, losing memory agent continuity

SOLUTION:
1. Semantic Renaming (clarity):
   - claudeSessionId → contentSessionId (user's observed session)
   - sdkSessionId → memorySessionId (memory agent's session for resume)
   - Database migration 17 renames columns accordingly

2. Memory Session ID Capture:
   - SDKAgent captures session_id from first SDK message
   - Persists to database via updateMemorySessionId()
   - SessionManager loads memorySessionId on session init

3. Resume Logic Fixed:
   - Only resume if memorySessionId captured from previous interaction
   - Enables memory agent continuity across user prompts

Files changed: 33 (types, database, agents, hooks, routes)
