Viktor Barzin 48225f2dea homelab CLI v0.7: add ha token + ha ssh for Home Assistant
Mined another devvm user's Claude sessions for repeated, hand-rolled command
patterns worth absorbing into the shared CLI. The dominant signal was Home
Assistant "Sofia" work: a `kubectl | base64 | jq` token-extraction pipeline
re-derived ~420x, and a bespoke non-interactive `ssh -o …` invocation reinvented
~30x — every session. The existing `home-assistant-sofia.py` already covers the
API but goes unused from an arbitrary cwd (needs an env var set + a cwd-relative
path), so agents bypassed it and hand-rolled everything.

Add two verbs covering exactly the gaps the `ha` MCP can't (entity state/control
stays with the MCP):
- `ha token [--instance sofia|london]` (read): resolves the long-lived API token
  live from k8s secret openclaw/openclaw-secrets via the ambient kubeconfig — no
  pre-set env var. Composes as `curl -H "Authorization: Bearer $(homelab ha token)"`.
- `ha ssh [--instance sofia|london] -- <cmd>` (write): deterministic
  non-interactive ssh to the HA host using the invoking user's key.

Also fix the root cause: `home-assistant-sofia.py` now falls back to
`homelab ha token` when its env var is unset (works from any directory), and the
home-assistant skill points agents at these verbs + `homelab metrics query`
instead of hand-rolled curls. README + ADR-0012 + AGENTS.md updated per the
per-verb-group convention.
