Add brain-dump CLI for token-efficient task management

- list/add/edit/done/show/nudged/recurring commands
- --due flag with priority-based nudge intervals (now=1d, soon=3d, someday=7d)
- Tab-separated output for minimal token usage
- Consolidated news cron jobs (8→2) using multi-time cron expressions

+## Brain Dump CLI
+
+Helper script: `~/clawd/bin/brain-dump`
+
+```bash
+brain-dump list [--priority now,soon] [--due] [--limit N]
+brain-dump add --text "..." --priority soon [--context "..."]
+brain-dump edit <id> [--text "..."] [--priority ...] [--context "..."]
+brain-dump done <id>
+brain-dump show <id>
+brain-dump nudged <id1>,<id2>,...
+brain-dump recurring [--when evening]
+```
+
+- Data: `memory/brain-dump.json`
+- `--due` filters by nudge interval: now=1d, soon=3d, someday=7d
+- `nudged` marks tasks as just-nudged (resets due timer)
+- `recurring` lists recurring reminders (nose shower etc.)
+- Output is tab-separated for minimal tokens
+
+**Heartbeat workflow:**
+1. `brain-dump list --due --limit 2` → get tasks needing a nudge
+2. Mention them conversationally
+3. `brain-dump nudged <id1>,<id2>` → mark as nudged
