TRACE v2.0.0

This release renames four commands. See "Moving to the single plugin" in deliverable/README.md before you update.

Changed

• TRACE is one plugin again. trace now holds every skill, script, hook, and the plan viewer. trace-plan, trace-git, and trace-full are gone from both marketplaces. /trace-plan:spec, /trace-plan:epic, /trace-git:commit-message, and /trace-git:pr-description are now /trace:spec, /trace:epic, /trace:commit-message, and /trace:pr-description. In Codex, $trace-full: becomes $trace:. claude plugin update trace@trace now updates everything. Before, updating trace-full left the skills on the old version. To move from the old plugins, follow "Moving to the single plugin" in deliverable/README.md. Settings, plans, and epics stay where they are (ADR 0013).
• The writing rules are about 40% shorter. authoring-rules.md, change-summary-style.md, and the commit-message and pr-description skills and examples went from about 5,860 words to about 3,550. The cuts remove rules stated in more than one file, worked examples of each test, and process steps the model now follows without them. Every rule about words, sentences, templates, and the delete test stays. Drafts for two PRs and four commits in this repo came out the same length and quality with the old and new rules. The new rules missed two things more often: sentences whose subject was an "-ing" verb, and bold bullet openings past 15 words. change-summary-style.md now names both as a last check.
