Ismar 195d95e00c feat(devin): expose handoff backend in MCP server enum (#3 )

The Devin MCP server's backend enum only listed mock/claude/codex/copilot,
excluding the handoff backend that was merged to the engine in #125. This
made the subscription-friendly, no-API-key path unavailable to Devin users
while Claude Code had a dedicated /skillopt-sleep-handoff command for it.

Add "handoff" to the backend enum in _TOOL_SCHEMA so sleep_run accepts
backend: "handoff". The engine already handles the prompt/answer file loop
(exit code 3 + .skillopt-sleep-handoff/); the MCP server needs no special
handling — it passes through the engine output showing pending prompts.

Update the README, rules snippet, and test_backends_in_enum accordingly.

SkillOpt-Sleep (Devin)

You have access to a nightly self-evolution cycle via the skillopt-sleep MCP server. Use these tools to improve your long-term skills over time:

sleep_status — refresh the converted local cache, then show how many nights have run and the latest staged proposal
sleep_dry_run — refresh the converted local cache and preview a cycle without engine staging/adoption; a real backend still makes provider calls
sleep_run — run a full cycle; stages a proposal by default, while an explicit auto_adopt may also update live files
sleep_adopt — apply the staged proposal, then sync the managed skill to .devin/skills/skillopt-sleep-learned/SKILL.md when project is the Devin workspace and that workspace already contains a .devin/ directory
sleep_harvest — debug: list the recurring tasks mined from recent sessions
sleep_schedule / sleep_unschedule — low-level shared-engine cron controls; the current scheduled command does not run Devin's conversion step, so do not use it as an unattended Devin-harvest workflow

When a user asks about the sleep cycle or skill evolution, prefer calling these tools over explaining the concept.

Always pass the absolute Devin workspace as project, especially for sleep_adopt. Default backend is mock (no provider calls). The claude, codex, and copilot backend values use the corresponding installed and authenticated CLI; they do not require this plugin to implement a separate API-key flow. The handoff backend runs the cycle with no model subprocess or API key — the engine writes pending model calls to .skillopt-sleep-handoff/ and exits; answer each prompt in a fresh context and re-run sleep_run to resume (typically 3–6 rounds).

The Devin conversion and mock workflow stay local. A real backend sends truncated transcript excerpts and derived tasks to the selected provider for mining, replay, judging, and reflection; conversion is not a guarantee that outbound prompts contain no secrets. Review local sources and provider policy before selecting a real backend.

For a reviewed task file, pass tasks_file; before using it with a real backend, inspect/redact it and ensure its metadata contains "reviewed": true.

Place this file at .devin/rules/skillopt-sleep.md in your workspace.
