Add the spec-kit-fixit community extension to the catalog. Fixit provides spec-aware bug fixing — maps bugs to spec artifacts, proposes a plan, and applies minimal changes.

Changes:

• Added fixit entry to extensions/catalog.community.json (alphabetical order)
• Added Fixit Extension row to the Community Extensions table in README.md

Testing

• Tested with a sample project (if applicable)

AI Disclosure

• I did use AI assistance (describe below)

AI was used to draft the fixit command.

extensions/catalog.community.json:379

• This entry key is no longer indented to match surrounding extension entries (e.g., "extensify" above). Please restore the standard indentation for keys under extensions to avoid a formatting regression in the catalog.

      "name": "Fix Findings",

extensions/catalog.community.json:396

• "hooks": 1 is missing indentation inside the provides object, which makes the JSON formatting inconsistent and harder to scan. Please reformat this block to match the surrounding indentation.

        "commands": 1,
"hooks": 1

• "created_at" is missing indentation compared to the other fields in this object. Please reformat this line (and any adjacent lines) to match the file’s standard 2-space indentation.

[Copilot]

The fix-findings entry has unintended whitespace/indentation changes (e.g., the top-level key at line 378, and also fields like hooks/created_at later in the same object). While JSON will still parse, this breaks the consistent formatting used by neighboring entries (e.g., extensify is indented under extensions) and creates noisy diffs. Please reformat this section to match the surrounding 2/4-space indentation (or run the repo’s JSON formatter) and avoid unrelated edits in a PR that’s only adding fixit.
