feat(skills)!: S4 night commands become drain, suspend and resume

Requirement 001 phase 6, S4 (decision 29):

- Skills renamed: kvb-org-evening -> kvb-org-drain, kvb-org-sunset ->
  kvb-org-suspend, kvb-org-sunrise -> kvb-org-resume, kvb-agent-relax
  -> kvb-agent-drain, kvb-agent-sleep -> kvb-agent-suspend,
  kvb-agent-wakeup -> kvb-agent-resume; their text uses the new verbs and
  every reference in skills, README, orchestrator and tests follows.
- night.py takes drain, suspend, resume, resume --alone and status. A
  state file written before the rename keeps working: mode evening reads
  as drain, sunset as suspend, the awake list as resumed and is rewritten
  on the next save; the hub's council.night_mode maps the same values.
  mode: day and handover_night_<session>.md keep their names.
- Orchestrator: the Day/Night menu shows Drain, Suspend and Resume, each
  confirmed, signed through /api/board/sign with the passkey and run as
  the existing argv job; the old action names are refused.
- kvb-skill-cleanup: git rates two renames at 44 and 50 % similarity,
  under its default threshold, so legacy.py detects renames from 40 %.
- tests/test_night_names.py fails on any old name in the tree outside a
  rename record "old ->".

BREAKING CHANGE: the six old skill names and night.py's clear and wake
are gone. Run make install (it reinstalls the orchestrator too), then
kvb-skill-cleanup to remove the old installed copies; until the install,
the running hub calls the old night.py path.

Evidence: make test 679 OK, ruff and markdownlint clean
(/tmp/s4-make-test-1.log); e2e 22 OK in Chromium and Firefox
(/tmp/s4-e2e-3.log); MEDUSA 23 files, the 2 findings are the
byte-identical atomic state write that moved with night.py, already
accepted after a skeptic at its old path, rescan 0 open.

🎯 Fix: 93 %
💥 Break: 4 %
💸 Cost: 100 %
⏱️ Time: –
🛡️ Security: 100 %
🏆 Score: 89
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
