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
