v1.0.0

Added

• SKILL.md: explicit template-placeholder substitution step — OWNER/REPO,
  OWNER_USERNAME, PROJECT_NAME, YYYY-MM-DD are replaced with the
  target repo's real values when templates are copied (badges, discussions,
  security advisory, clone URLs no longer ship broken)
• SKILL.md metadata: requires now lists jq + python3 alongside
  gh / git (they were already needed by Module A)
• SKILL.md Module D: documents $default-branch triggers and lockfile-aware
  dependency install for Node projects
• SKILL.md Module B: issue forms now also follow the user's chosen language
  (Preflight step 5)

Changed

• CI templates: push.branches: [main] → [$default-branch] — workflows
  now trigger on any default branch name (Node / Python / Go / Rust)
• ci-node.yml: dependency install detects the lockfile (npm ci /
  pnpm install --frozen-lockfile / yarn install --frozen-lockfile /
  plain npm install fallback)
• ci-go.yml: matrix updated to Go 1.25 / 1.26 (1.22 / 1.23 were EOL)
• templates/labels.json: P3 color 0e8a16 → 1a7f37 so it no longer
  duplicates status: ready to merge's color
• templates/CONTRIBUTING.md: PR target wording no longer hardcodes main
• VISION.md: current state reflects v1.0
• Repo labels dogfooded to the v1 baseline: P0–P3 and impact:* added

Removed

• Legacy priority: critical/high/medium/low labels from this repo
  (superseded by P0–P3)
