Add hunk-commit to hunk-extension marketplace

[benvinegar]

Problem

hunk-commit (muzomer/hunk-commit) lets you mark hunks while reviewing in
Hunk and move them without leaving the review — into the git index, or into a
commit: a git commit, or a Jujutsu revision. Your files on disk never change.
It is tagged hunk-extension and installable today, but the directory does
not list it, so the only way to find it is the GitHub topic.

Approach

One entry appended to EXTENSION_CATALOG in website/src/data/extensions.ts,
in the file's existing order (alphabetical by owner, after modem-dev's own
entries), between mikeclarke/hunk-tutor and phl28/hunk-gh-review.

Every field is taken from the extension's own manifest: name and version
from package.json, apiVersion from its hunk block, repo exactly as
hunk extension install accepts it.

categories names the surfaces it registers (checked in its index.ts):
registerCommand (mark/unmark hunk, mark/unmark file, clear marks, stage,
commit, commit with body, put into an existing commit, discard) and
registerLineHighlighter (marked hunks painted amber).

Non-goals: no change to the page, the schema, or the build-time topic fetch.

Verification

• bun test scripts/check-extension-catalog.test.ts — 9 pass, 0 fail
• bunx oxlint website/src/data/extensions.ts --deny-warnings — 0 warnings, 0 errors
• Empty changeset included, since this is a directory listing rather than a
  change to hunkdiff behaviour.

Greptile Summary

Adds hunk-commit to the extension marketplace catalog.

• Lists its repository, description, supported capability categories, package version, and minimum extension API version.
• Adds an empty changeset for the directory-only update.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness, security, or compatibility issues identified.

The new catalog entry conforms to the existing schema, category values, ordering, installation-command format, and documented extension API compatibility semantics.

Important Files Changed

Filename	Overview
website/src/data/extensions.ts	Adds a schema-valid, correctly ordered marketplace entry whose categories and installation identifier conform to existing catalog contracts.
.changeset/hunk-commit-extension.md	Adds the expected empty changeset for a directory listing that does not alter published package behavior.
