Add Cleanup Extension to catalog

[dsrednicki]

Extension: Cleanup Extension

Repository: https://github.com/dsrednicki/spec-kit-cleanup
Version: 1.0.0
License: MIT
Author: @dsrednicki

What it does

Post-implementation quality gate that reviews changes and handles issues by severity:

Severity	Examples	Action
SMALL	Debug statements, unused imports, dead code	Fix immediately (Scout Rule)
MEDIUM	Missing error handling, code duplication	Create follow-up tasks in tasks.md
LARGE	Architecture issues, security design flaws	Generate tech-debt-report.md with options
CRITICAL	Hardcoded secrets, disabled auth	Halt and alert user

Key features

• Scout Rule: Automatically fixes small mechanical issues with user confirmation
• Constitution Compliance: All cleanup actions respect project constitution principles
• Non-Destructive: Always confirms before modifying, rolls back on validation failure
• Linter Integration: Defers to project linters for style issues
• Tech Debt Tracking: Creates actionable tasks and detailed reports

Commands

Command	Description
/speckit.cleanup.run	Review implementation, fix small issues, identify tech debt
/speckit.cleanup	Alias for above

Hook

• after_implement - Prompts to run cleanup after /speckit.implement completes

@dsrednicki You will have to host it on a GitHub repo you own similar to the V-Model extension does, see #1640 and the repository for the extension itself at https://github.com/leocamello/spec-kit-v-model

I hope that clarifies it enough? Feel free to ask more questions.

Tagging @leocamello as well as he just went through the process and might be available to answer questions as well
