feat: sync all 4 runtime plugins with full engine surface + fix #52 #58 #62

Bug fixes:
- #52: bundle run-sleep.sh in Claude Code plugin + 4-level fallback
- #58: add skillopt-sleep console script entry point in pyproject.toml
- #62: filter headless claude -p replay sessions from harvest

Plugin sync (Claude Code / Codex / Copilot / OpenClaw):
- Document all 22 CLI flags, 7 actions, 4 backends across all SKILL.md files
- Document config keys (preferences, gate_mode, dream_rollouts, etc.)
- Document memory consolidation (evolve_memory / evolve_skill)
- Add schedule/unschedule to all plugins
- Copilot MCP: expand schema from 3 → 16 params + schedule tools
- OpenClaw: add schedule/unschedule subcommands via shared scheduler

Tests:
- Cross-plugin parity test (prevents future feature drift)
- MCP schema completeness test

+### Scheduling
+
+```bash
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" schedule --project "$(pwd)" --hour 3 --minute 17
+bash "$SKILLOPT_SLEEP_REPO/plugins/run-sleep.sh" unschedule --project "$(pwd)"
+```
+
+Installs a nightly cron entry. `unschedule --all` removes every managed entry.
+
+### All backends
+
+- `--backend mock` — deterministic, no API spend (default)
+- `--backend claude` — uses the Claude CLI
+- `--backend codex` — uses the Codex CLI
+- `--backend copilot` — uses the GitHub Copilot CLI
+
+### Additional flags
+
+| Flag | Description |
+|------|-------------|
+| `--auto-adopt` | Auto-adopt if the gate passes (default: stage only) |
+| `--edit-budget N` | Max bounded edits per night (default: 4) |
+| `--lookback-hours N` | Harvest window in hours (default: 72) |
+| `--json` | Machine-readable JSON output |
+
+### Config keys (`~/.skillopt-sleep/config.json`)
+
+- **`preferences`** — free-text house rules for the optimizer
+- **`gate_mode`** — `on` (validation-gated, default) or `off` (greedy)
+- **`gate_metric`** — `hard` | `soft` | `mixed` (default)
+- **`dream_rollouts`** — >1 for multi-rollout contrastive reflection
+- **`recall_k`** — >0 recalls similar past tasks from the archive
+
+### Memory consolidation
+
+The sleep cycle consolidates both **memory** (AGENTS.md / CLAUDE.md) and **skills** (SKILL.md) by default. Each is independently toggleable via `evolve_memory` / `evolve_skill` config keys. Both are gated by the same held-out validation score.

 ## Steps
 
 1. Run the requested action; capture stdout.
