feat(refine): remove condense skill and its hook

[blafourcade]

🎯 What & why

Removes aidd-refine:03-condense and the UserPromptSubmit hook that backed it. The skill overlapped with the host tool's own output settings, and its 02-stats action depended on the model emitting a literal Condense: ON (<level>). marker that it paraphrased in practice — a limitation the eval harness already documented as a known finding rather than a bug worth fixing.

🛠️ How it works

Three moves, in order:

1. Delete skills/03-condense/ and hooks/. hooks.json registered only the condense hook, so the whole directory goes rather than leaving an empty manifest behind. aidd-context is now the only plugin shipping hooks — docs/ARCHITECTURE.md drops to a single row.
2. Renumber to stay contiguous, via git mv so rename detection survives review: 04-shadow-areas → 03-shadow-areas, 05-fact-check → 04-fact-check. Both SKILL.md frontmatter name: fields follow.
3. Chase every reference. Nothing outside the plugin cited the moved skills — a repo-wide sweep found only aidd-refine:01-brainstorm and aidd-refine:02-challenge referenced from other plugins (checker.md:46, 03-check.md:26, the cook recipes, idle-menu.md), and neither moves. So the renumber is safe for every other plugin.

Two details worth a reviewer's eye:

• plugin.json and marketplace.json carried a byte-identical description string mentioning "condensed communication mode". Both are rewritten to the same new string so they can't drift.
• 02-verify.md:24 used hooks/condense-stats.js as its worked example of a file that exists. Deleting the hook would have inverted the test, so the example now points at plugins/aidd-context/hooks/update_memory.js.

CATALOG.md and the README counts are auto-generated; both were regenerated with the exact invocations from lefthook.yml rather than hand-edited.

Deliberately untouched: cli/tests/fixtures/framework-real/ is a pinned v4.1.0-beta.12 snapshot with its own refresh script, and framework-build-golden.e2e.test.ts:34 builds from that fixture rather than the live tree — so the condense strings still in golden.json are correct and must stay. CHANGELOGs are history.

🧪 How to verify

Run the real pre-commit gates:

node scripts/validate-json.mjs .claude-plugin/marketplace.json plugins/aidd-refine/.claude-plugin/plugin.json
node scripts/check-skill-argument-hints.mjs
node scripts/check-markdown-links.js --ignore cli/tests/fixtures --ignore cli/aidd_docs/tasks
node scripts/sync-readme-counts.mjs --check

All four pass on this branch (✅ Links: 0 broken in 673 files; README settles at 4 skills for aidd-refine, 47 total).

Confirm nothing stale is left behind:

grep -rn "03-condense\|04-shadow-areas\|05-fact-check" \
  --exclude-dir={node_modules,.git,fixtures,snapshots} . | grep -v CHANGELOG

Returns nothing.

⚠️ Heads-up

• Breaking for pinned references. Anyone invoking aidd-refine:04-shadow-areas or aidd-refine:05-fact-check by name must update to the new numbers. The commit carries BREAKING CHANGE: so release-please bumps aidd-refine accordingly; .release-please-manifest.json is left at 2.2.4 for the tooling to own.
• The 03-condense eval case is removed from scripts/skill-eval/cases.json, and its entry under "Known findings" in the harness README goes with it.
