docs(core): point generated Claude notes at skills, not path-glob rules

[TimCrooker]

Every generated CLAUDE.md currently tells the consuming repo:

Reserve .claude/rules/*.md for narrow path-glob injections only.

The pattern that holds up better is a skill carrying the procedure or standard, plus a scoped CLAUDE.md that points at it — the slice auto-loads in the directories where the work happens, and the depth lives in the skill rather than being injected wholesale on every file touch. The generated note now says that.

Also drops "rule file" from the module-target error in config.ts. It steered readers toward rules while explaining an unrelated config mistake (a module declaring a non-root target).

Rules remain fully supported — claudeRulesDir, claudeRuleFile, and claudePaths are untouched. This only changes what the kit recommends in generated output.

examples/listforge-like regenerated with the CLI. examples/gauntlet was hand-edited on the same line because that fixture currently fails to build for an unrelated reason (010-overview.md declares target api, and modules only compose into the root output) — worth a separate fix.

223 tests pass. Pre-existing prettier warnings on the touched files are left as they were rather than reformatting 114 files in this PR.

Note

Update generated Claude notes to reference .ai/skills/* instead of path-glob rules

• Updates the guidance bullet in render.ts so generated CLAUDE.md files now direct users to put procedures in .ai/skills/* and reference them from a scoped CLAUDE.md, replacing the old advice to use .claude/rules/*.md for path-glob injections.
• Updates the same bullet in the example gauntlet/CLAUDE.md and listforge-like/CLAUDE.md to match.
• Adjusts the error message in config.ts when a module targets a non-root scope to say "its own file" instead of "a rule file".
