test: skill-fixture helper — extract SKILL.md sections, don't copy files

extractSkillSections (fence-aware H2 scanner, loud-throw on missing
sections with available-heading list), extractSkillBody (drops the
shared generated preamble), extractSkillHead (frontmatter + first 30
lines, for routing fixtures). Pinned section lists per consumer, and
free-tier real-skill pins so a gen-skill-docs heading rename fails the
FREE suite instead of a paid run. skill-fixture.ts joins
GLOBAL_TOUCHFILES (fail-safe polarity: over-select).

/**
* Skill fixture extraction — enforces the CLAUDE.md rule "E2E test fixtures:
* extract, don't copy".
*
* Full SKILL.md files are 1000-1900 lines. When `claude -p` (or `codex exec`)
* reads a file that large, context bloat causes timeouts, flaky turn limits,
* and tests that take 5-10x longer than necessary. Every E2E fixture that
* needs skill content should extract ONLY the sections the test actually
* exercises, through one of the three helpers here:
*
* - extractSkillSections(skillDir, sections)
* frontmatter + the named `## <section>` blocks, concatenated in the
* order given. For tests that exercise specific workflow steps.
* - extractSkillBody(skillDir)
* frontmatter + intro + everything AFTER the shared generated preamble
* ("## Preamble (run first)" .. end of "## Plan Status Footer").
* For tests that exercise the skill's ENTIRE specific flow but never
* touch the ~780-line shared preamble.
* - extractSkillHead(skillDir, bodyLineCount)
* frontmatter + the first N body lines. For ROUTING / discovery tests,
* where the agent only reads the frontmatter (name + description) to
* decide which skill to invoke.
*
* Failure polarity: every extraction failure (missing file, missing
* frontmatter, renamed section) THROWS with the offending name — a fixture is
* never silently written empty. test/skill-fixture.test.ts pins the exported
* section lists against the real generated SKILL.md files, so a section
* rename fails the FREE suite instead of a paid E2E run.
