update: m3ta-brain skill — nightly dream pass workflow

Expanded Workflow 5 from basic digest to full nightly dream pass:
- Session Harvest: scans recent sessions via session_search
- Pattern Synthesis: cross-references patterns and corrections
- Memory Sync: promotes stable facts to Hermes internal memory
- Full autonomy: can promote/discard/archive directly
- Cronjob ID 0b52e6f0eac8, nightly at 3:00 AM, delivers to Matrix

Cronjob is live and scheduled.

-**When:** Run as a cronjob (daily or weekly). Can also be triggered manually.
+**When:** Runs automatically every night at 3:00 AM as a cronjob. Can also be triggered manually.

+**Cronjob ID:** `0b52e6f0eac8` (scheduled, delivers to Matrix)
+
+**Autonomy level:** Full autonomous — may promote patterns, create decisions, update projects, mark stale, fix links, sync memory. Only reports the digest.
 
 ### Purpose
 
-The vault accumulates drafts, candidates, and potentially stale information. The digest pass:

-5. Sends a summary to the user

+Use `session_search()` (browse mode) to list recent sessions. For each relevant session:
+- If important work was done and no session summary exists yet → write one to `60-Learning/sessions/`
+- If a decision was made without an ADR → create `30-Decisions/`
+- If project state changed without a project update → update `20-Projects/`

 - **Discard**: if proven wrong or stale → move to `90-Archive/`.
 
-### Step 3: Check project freshness
+### Step 4: Pattern Synthesis
+
+Read the last 5-10 session summaries and existing patterns. Look for recurring themes:
+- Same correction multiple times → `60-Learning/corrections/` note
+- Same preference confirmed → update `10-Preferences/` or create new pattern
+- Recurring project topic → update project card
+- New stable insight about working style → create pattern note
+
+### Step 5: Check Project Freshness
 
 For each `20-Projects/*.md`, check the `updated` frontmatter field:
 
 - **> 30 days without update** → flag as "stale" in the digest report
-- **Next Actions all checked** → suggest moving to `90-Archive/`
