feat(hermes): implement intelligence pipeline — 4 chunks, 684 tests passing

Hermes Intelligence Pipeline closes breakpoints in ZCLAW's existing
intelligence components with 4 self-contained modules:

Chunk 1 — Self-improvement Loop:
- ExperienceStore (zclaw-growth): FTS5+TF-IDF wrapper with scope prefix
- ExperienceExtractor (desktop/intelligence): template-based extraction
  from successful proposals with implicit keyword detection

Chunk 2 — User Modeling:
- UserProfileStore (zclaw-memory): SQLite-backed structured profiles
  with industry/role/expertise/comm_style/recent_topics/pain_points
- UserProfiler (desktop/intelligence): fact classification by category
  (Preference/Knowledge/Behavior) with profile summary formatting

Chunk 3 — NL Cron Chinese Time Parser:
- NlScheduleParser (zclaw-runtime): 6 pattern matchers for Chinese time
  expressions (每天/每周/工作日/间隔/每月/一次性) producing cron expressions
- Period-aware hour adjustment (下午3点→15, 晚上8点→20)
- Schedule intent detection + task description extraction

Chunk 4 — Trajectory Compression:
- TrajectoryStore (zclaw-memory): trajectory_events + compressed_trajectories
- TrajectoryRecorderMiddleware (zclaw-runtime/middleware): priority 650,
  async non-blocking event recording via tokio::spawn
- TrajectoryCompressor (desktop/intelligence): dedup, request classification,
  satisfaction detection, execution chain JSON

Schema migrations: v2→v3 (user_profiles), v3→v4 (trajectory tables)
