v12.8.0 — cc10x-guide skill + documentation overhaul

User feedback drove a documentation-first release: the README was a reference manual instead of a landing page, and the plugin shipped no way to ask Claude about cc10x itself. Two behavioral fixes fell out of the setup-correctness audit.

Added

• New skill: cc10x-guide (19 → 20 skills) — model-invoked help desk for cc10x itself. Answers "what is cc10x", "how do I configure it", "why isn't it activating" with short authoritative answers plus pointers to the canonical on-disk files (README sections, claude-settings-template.json, memory contract, router references). Lean (~145 lines), pointer-based, read-only by contract — negatively scoped in its description so work requests still route to cc10x-router and upgrades to the update skill.
• README restructured for the <5-minute user — Quick Start moved directly under Install; How It Works reduced to one diagram + one paragraph; all architecture content collapsed into a <details> deep dive; version history collapsed; HTML explorers linked from the hero. No content deleted — everything moved or folded.

Fixed

• Setup-created patterns.md violated the memory contract. The README setup flow emitted ## Architecture Patterns / ## Code Conventions and omitted the contract-required ## Project SKILL_HINTS Edit anchor — agents anchoring to that heading failed against setup-created files. The setup template now emits exactly the canonical headings from memory-file-contracts.md.
• Permission templates unified. README and claude-settings-template.json had drifted in both directions and both missed commands every workflow runs. Both now carry the same 14-entry list, adding Bash(git rev-parse:*) (phase base SHAs), Bash(python3:*) (router-run review_package.py / phase_brief.py), Bash(git blame:*), Bash(git branch:*), and Bash(mkdir -p docs/solutions). Write(docs/*) remains unprompted-by-default deliberately — outward-facing artifacts keep their approval friction.

Changed

• doc_consistency_check.py extended — now also asserts marketplace.json's metadata.version and plugins[0].version match plugin.json, closing the version-drift seam on the marketplace install surface.
• Version bumped to 12.8.0 in all locations: plugin.json, marketplace.json (3 strings), README banner + footer, docs status notes (5 files).

Skill count

19 → 20 skills (excluding router, per doc_consistency_check.py counting rule)
