Follow-up to #125. Two resumability defects in the handoff driver:
1. A no-task night left digests.json (often []) pinned, so every later run
reloaded the empty pin and never called harvest_for_config again. Remove the
pin on terminal no-task completion so the next run re-harvests.
2. An interrupted/corrupt tasks.json snapshot raised an uncaught
JSONDecodeError in _run_handoff. Wrap load_tasks_file in try/except and
re-mine instead of crashing.
Adds regression tests for both.

Adds --backend handoff: the engine runs all deterministic stages and
outsources attempt/judge/reflect to prompt/answer files an interactive
agent session fills between runs (exit 3 = pending batch, re-run to
resume). Deterministic replay + the prompt-hash answer cache make resume
stateless; sentinel detection aborts any call built from unanswered
output so placeholders never reach scores or staging. Session digests
and mined tasks are pinned per night (secret-redacted) so the sessions
answering prompts cannot shift the task set, and LLM mining is routed
through the same handoff files. Ships a /skillopt-sleep-handoff Claude
Code command that answers each prompt in a fresh-context subagent to
protect the held-out gate.

Codex round 3: argparse default=0 made every CLI invocation without
--lookback-hours clobber the config's 72h default. Now default=None;
only explicit --lookback-hours N (including 0) overrides config.

- harvest.py: revert break to continue — mtime ordering can diverge
from embedded ended_at timestamps (copy/touch), so we must check all
files rather than early-exiting on the first old one
- cycle.py: use `is not None and > 0` so lookback_hours=0 means
"scan full history" (opt-out of the cutoff)
- __main__.py: propagate --lookback-hours 0 to config as explicit 0

Add CopilotCliBackend that drives the GitHub Copilot CLI in
non-interactive mode (copilot -p ... --output-format json) and parses the
JSONL event stream for assistant.message content. Registered as the
'copilot' backend (with aliases) and wired through the CLI, config,
experiment harness, and the Copilot MCP server's backend enum.
- Force UTF-8 decoding of CLI output (fixes cp1252 UnicodeDecodeError on
Windows when responses contain non-cp1252 bytes).
- Minimise per-call startup: isolated COPILOT_HOME with built-in MCPs and
custom instructions disabled, so user MCP servers are not spawned per
call (~5x faster: 36s -> 7.4s). Override via SKILLOPT_SLEEP_COPILOT_HOME
/ SKILLOPT_SLEEP_COPILOT_MODEL / SKILLOPT_SLEEP_COPILOT_FULL_ENV.
Validated end-to-end on real held-out tasks (researcher persona:
0.42 -> 1.00 lift; gate correctly rejects non-improving edits).

Updates the SkillOpt-Sleep plugin on top of the current main. User-facing and
engine improvements since the initial drop:
* Command renamed /sleep -> /skillopt-sleep across Claude Code + Codex shells;
refreshed plugin READMEs and install scripts.
* Built-in scheduling (skillopt_sleep/scheduler.py + __main__): schedule /
unschedule the nightly cycle without external cron wiring.
* Backend robustness: bounded retry with backoff (no more silent empty-string
on transient 429/timeout), content-filter-safe rollout prompt, an
output-contract guardrail that rejects edits violating the task's required
format, and a per-sample cache key so repeated dream rollouts are independent
samples (fixes degenerate single-sample reflection).
* consolidate / rollout / replay: parallel multi-rollout dreaming, gate-mode
controls, TaskRecord.system framing field.
Scope: this commit ships only the plugin engine + shells. Research/benchmark
harnesses and their data are intentionally not included; the public package
has no dependency on them (the one research-evaluator import is now guarded).
Marked as an early preview in the README; we'll keep iterating.
99/99 unit tests pass.

Open-source-tool / research-code separation:
- git mv skillopt/sleep/ -> skillopt_sleep/ (top-level, sibling to the research
skillopt/ package). History preserved as renames.
- All imports skillopt.sleep.* -> skillopt_sleep.*.
- Vendor the validation gate into skillopt_sleep/gate.py (a self-contained copy
of skillopt.evaluation.gate). The engine now has ZERO dependency on the
research package — verified: grep finds no `from skillopt.` in skillopt_sleep/,
and consolidate's gate resolves to skillopt_sleep.gate.
- Plugin scripts/commands/skill call `-m skillopt_sleep`.
29 tests pass; `python -m skillopt_sleep` runs standalone.
