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

 - Scope defaults to the invoked project; `--scope all` harvests every project.
 
+### Scheduling
+
+```bash
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" schedule --project "$(pwd)" --hour 3 --minute 17
+"${CLAUDE_PLUGIN_ROOT}/scripts/sleep.sh" unschedule --project "$(pwd)"

+## All CLI flags
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--project PATH` | cwd | Project directory to evolve |
+| `--scope all\|invoked` | invoked | Harvest scope |
+| `--backend mock\|claude\|codex\|copilot` | mock | Replay backend (mock = no API spend) |
+| `--model NAME` | backend default | Override the model used for replay |
+| `--source claude\|codex\|auto` | claude | Transcript source |
+| `--lookback-hours N` | 72 | Harvest window |
+| `--max-sessions N` | unlimited | Cap harvested sessions |
+| `--max-tasks N` | 40 | Cap mined tasks |
+| `--target-skill-path PATH` | auto | Explicit SKILL.md to evolve |
+| `--tasks-file PATH` | — | Reviewed TaskRecord JSON (skip harvest) |
+| `--progress` | off | Print phase progress to stderr |
+| `--auto-adopt` | off | Auto-adopt if gate passes |
+| `--edit-budget N` | 4 | Max bounded edits per night |
+| `--json` | off | Machine-readable JSON output |
+
+## Config keys (`~/.skillopt-sleep/config.json`)
+
+Beyond the CLI flags, advanced behavior is controlled via config:
+
+- **`preferences`** — free-text house rules injected into the optimizer's reflect step (e.g. "Always use async/await", "Answers in `\boxed{}`").
+- **`gate_mode`** — `on` (default, validation-gated) or `off` (greedy, accept all edits).
+- **`gate_metric`** — `hard`, `soft`, or `mixed` (default). Controls how the held-out gate scores.
+- **`dream_rollouts`** — >1 enables multi-rollout contrastive reflection per task.
+- **`recall_k`** — >0 recalls K similar past tasks into the dream (long-term memory).
+- **`evolve_memory`** / **`evolve_skill`** — independently toggle CLAUDE.md vs SKILL.md consolidation.
+
+## Memory consolidation
+
+The sleep cycle can consolidate both:
+- **SKILL.md** — the managed skill file (bounded edits: add/delete/replace)
+- **CLAUDE.md** — the project memory (same bounded edits)
+
+Both are gated by the same held-out validation score. Set `evolve_memory: false` to consolidate only skills, or `evolve_skill: false` for only memory.
+
 ## Hard rules
 
 - **Never** hand-edit the user's `CLAUDE.md` / `SKILL.md` as part of this skill.
