feat: add context overflow guard script (#510)

- Monitors tmux pane context levels
- 60% threshold: triggers summarization prompt
- 80% threshold: urgent commit and restart
- Logs context levels to tmux-state.json
- Supports --daemon and --status modes

Closes #510

+Context Overflow Guard Script
+Issue #510: [Robustness] Context overflow automation — auto-summarize and commit
+
+Monitors tmux pane context levels and triggers actions at thresholds:
+- 60%: Send summarization + commit prompt
+- 80%: URGENT force commit, restart fresh with summary
+- Logs context levels to tmux-state.json
+
+Usage:
+  python3 context-overflow-guard.py              # Run once
+  python3 context-overflow-guard.py --daemon     # Run continuously
+  python3 context-overflow-guard.py --status     # Show current context levels

+# Nightly Pipeline Scheduler
+
+Auto-starts batch pipelines when inference is available.
+
+## What It Does
+
+1. Checks inference provider health (OpenRouter, Ollama, RunPod)
+2. Checks if it's off-peak hours (configurable, default: after 6PM)
+3. Checks interactive session load (don't fight with live users)
+4. Checks daily token budget (configurable limit)
+5. Starts the highest-priority incomplete pipeline
+
+## Pipeline Priority Order
+
+| Priority | Pipeline | Deps | Max Tokens |
+|----------|----------|------|------------|
+| 1 | playground-factory | none | 100,000 |
+| 2 | training-factory | none | 150,000 |
+| 3 | knowledge-mine | training-factory running | 80,000 |
+| 4 | adversary | knowledge-mine running | 50,000 |
+| 5 | codebase-genome | none | 120,000 |
+
+## Usage
+
+```bash
+# Normal run (used by cron)
+./scripts/nightly-pipeline-scheduler.sh
+
+# Dry run (show what would start)
+./scripts/nightly-pipeline-scheduler.sh --dry-run
+
+# Status report
+./scripts/nightly-pipeline-scheduler.sh --status
+
+# Force start during peak hours
+./scripts/nightly-pipeline-scheduler.sh --force
+```
+
+## Configuration
+
+Set via environment variables:
+- `PIPELINE_TOKEN_LIMIT`: Daily token budget (default: 500,000)
+- `PIPELINE_PEAK_START`: Peak hours start (default: 9)
+- `PIPELINE_PEAK_END`: Peak hours end (default: 18)
+- `HERMES_HOME`: Hermes home directory (default: ~/.hermes)
+
+## Cron
+
+Runs every 30 minutes. Off-peak only (unless --force).
+See `cron/pipeline-scheduler.yml`.
