* refactor(skill): shorten hassio-addon-workflow via progressive disclosure

SKILL.md was 365 lines, loaded in full on every add-on task. Split it per
Anthropic's Agent Skills best practices: keep steps, completion criteria,
and the mechanism ladder inline; push rationale, war-story examples, and
Codex CLI invocation details into reference files loaded only when that
branch is taken.

- SKILL.md: 365 -> 171 lines. The "ship the simplest solution" rule was
  stated three times; now once. Steps 3/6/9 keep their load-bearing
  checklist but point to detail files instead of inlining it.
- references/evidence.md (new): measurement methodology, the
  host-generalization failure examples, the merged-and-inert case studies
- references/codex-review.md (new): CLI invocation, prompt guidance,
  plan-attack checklist
- references/simplify.md (new): mechanism-ladder case studies

Also replaces the old "Token efficiency" section (which named this
maintainer's personal MCP tools - rtk/headroom/tokensave - not guaranteed
present for CI agents or other collaborators using the checked-in copy)
with a subagent-delegation instruction: Codex's plan/code review and
PR-comment triage on >5 threads should run in a subagent that returns a
condensed summary, not raw output, into the calling session.

* fix(skill): address PR review feedback

- SKILL.md: define $SKILL once and state that all scripts/ and references/
  shorthand paths are relative to it — they read as repo-root-relative
  otherwise and don't resolve from an add-on directory
- codex-review.md: drop the reference to a "global CLAUDE.md note" that
  isn't in this repo's CLAUDE.md; describe --sandbox read-only accurately
  (reads allowed, writes/exec blocked, approvals disabled) instead of
  "cannot run anything"; add the missing & so the example is actually
  backgrounded as the prose claims
- evidence.md: use smaps_rollup for process RSS — plain smaps prints one
  Rss: line per mapping (47 for a trivial process here), not a total
- simplify.md: drop the absolute "removals cannot regress" claim, which
  contradicted the /dev/shm case study in evidence.md

* refactor(skill): apply independent quality-review findings

From an independent model review of the skill against the Agent Skills
best-practice guides:

- traps.md: CHANGELOG was described as "the only hard gate", contradicting
  SKILL.md — the HA add-on linter and the image build also block PRs
  (verified against onpr_check-pr.yaml). Gates list corrected.
- codex-review.md: the "attack your own plan" checklist is run by the main
  agent, but lived in the file whose stated consumer is the delegated
  subagent — an agent that delegates correctly would never see it. Moved
  inline into SKILL.md step 3.
- SKILL.md: delegation instruction now says exactly what to do (spawn a
  subagent whose prompt includes references/codex-review.md and follows its
  invocation) instead of "delegated per the rule above".
- SKILL.md: traps.md is no longer mandatory reading on the light path —
  the light-path facts it holds (versioning, CHANGELOG format) are inline
  in step 7; it stays required when touching scripts/Dockerfiles/env.
- SKILL.md: dropped the bundled-files table (every row already cited at
  point of use) and the "read the script when you use it" anti-instruction
  — scripts are run, not read. 177 -> 167 lines.
- description: 982 -> 550 chars; removed workflow narrative that does
  nothing for skill selection and the stale-prone model name, kept all
  trigger terms.

* fix(skill): note that CI hard gates skip on non-addon PRs

The three hard gates in onpr_check-pr.yaml (changelog check, addon-linter,
check-build) are each matrixed over check-addon-changes.outputs.changedAddons
and if:-skipped when it is '[]'. A PR touching only docs, .github/ or .claude/
therefore shows them as "skipping" rather than passing — which should not be
read as a green build. Verified against onpr_check-pr.yaml lines 64, 83, 101
and against this PR's own check output.
