chore: Bump version to 0.4.0

Key fix: Orphan cleanup now skips Claude processes in valid Gas Town
tmux sessions (gt-*/hq-*), preventing false kills of witnesses,
refineries, and deacon during startup.

Updated all component versions:
- gt CLI: 0.3.1 → 0.4.0
- npm package: 0.3.0 → 0.4.0

-1. **Use `--continue` for propulsion** - Keep momentum by auto-advancing
-2. **Check progress with `bd mol current`** - Know where you are before resuming
-3. **Squash completed molecules** - Create digests for audit trail
-4. **Burn routine wisps** - Don't accumulate ephemeral patrol data
+1. **CRITICAL: Close steps in real-time** - Mark `in_progress` BEFORE starting, `closed` IMMEDIATELY after completing. Never batch-close steps at the end. Molecules ARE the ledger - each step closure is a timestamped CV entry. Batch-closing corrupts the timeline and violates HOP's core promise.

-### Closing Steps (for Activity Feed)
+### 🚨 THE BATCH-CLOSURE HERESY 🚨
+
+Molecules are the **LEDGER** - not a task checklist. Each step closure is a timestamped entry in your permanent work record (your CV).
+
+**The discipline:**
+1. Mark step `in_progress` BEFORE starting it: `bd update <step-id> --status=in_progress`
+2. Mark step `closed` IMMEDIATELY after completing it: `bd close <step-id>`
+3. **NEVER** batch-close steps at the end
+
+**Why this matters:** Batch-closing corrupts the timeline. It creates a lie - showing all steps completed at the same moment instead of the actual work progression. The activity feed should show your REAL work timeline.
+
+**Wrong:** Do all work, then close steps 1, 2, 3, 4, 5 in sequence at the end
+**Right:**
+- Mark step 1 in_progress → do work → close step 1
+- Mark step 2 in_progress → do work → close step 2
+- (repeat for each step)
 
-As you complete each molecule step, close it:
 ```bash
 bd close <step-id> --reason "Implemented: <what you did>"
 ```
