Rewrite CodeceptJS skills: bullets over prose, doc-verified content, cross-references

[DavertMik]

Summary

Rewrite of all 13 skills under plugins/codeceptjs/skills/ following three principles:

• Bullets over prose — workflows compressed to numbered steps, structured sections instead of long paragraphs
• Keep only what a model would get wrong — non-obvious rules and traps stay; CLI flags, API catalogs, and doc paths that are discoverable via --help, codeceptjs list, or node_modules/codeceptjs/docs/ are cut
• Cross-references between skills — each skill names which to run first and which to hand off to, matching exact section names (codeceptjs-fundamentals § Effects, § Plugins from CLI)

Per-skill changes

Skill	Change
codeceptjs-fundamentals	Restructured into Gate / Main rule / Where things go / Shortcuts / Architecture / Config mutation trap / Plugins / Effects / Element-based API / Assertions. Content verified against current codecept.io docs: setCommonPlugins() bundle (enables retryFailedStep + screenshot; registers pause, browser, aiTrace, heal), lazy-proxy DI rationale, ARIA-first locator priority, effects API (tryTo/retryTo/hopeThat/within), codeceptjs/els, assertion preference ladder (custom helper → ExpectHelper → codeceptjs/assertions → external), soft assertions via hopeThat.noErrors(). Low-level access in Scenarios softened to a recommendation
writing-codeceptjs-tests	218 → 106 lines. Workflow to numbered steps; kept dry-run-skips-plugins warning, aiTrace MCP-vs-CLI asymmetry, I.see context requirement, step.opts disambiguation
debugging-codeceptjs-tests	234 → 130 lines. Cut 25-row tool-selection table (duplicated workflow); collapsed repeated pause() explanations into Paths section; condensed codeceptq to essentials
refactoring-codeceptjs-tests	Compressed; decision tree kept intact; aligned with fundamentals' "Where things go" vocabulary
codeceptjs-auth	Fixed typos ("nto", "includded", "accross", "sessision"); merged Verify/Refactor sections; kept ask-first questions and config shapes
codeceptjs-run-analysis / codeceptjs-exploration / ci-fix-tests	Bullet compression, trimmed pointers, cross-refs
4 framework migrations + migrate-codeceptjs-4	Surgical: translation tables and hard rules untouched; duplicated doc-path Pointer lists (~15 bullets each) replaced with Related skills + one docs line; identical batch-run prose compressed to bullets

Net: −223 lines across the set.

Test plan

• No Pointers sections remain (grep -c Pointers clean)
• Spot-read fundamentals against codecept.io/basics, /pageobjects, /effects, /assertions, /element-based-testing
• Confirm cross-referenced section names exist in target skills
