catalog: note the Kestrel name for grloper/dsh-deep-research

[grloper]

Updates the existing grloper/dsh-deep-research entry only.

The project's engine name changed from VERITAS to Kestrel in v0.3. This prefixes both descriptions with the new name so the catalog matches the repository, README, and social card. The id, repository, category, filename, and added date are unchanged, and the described behaviour is identical.

Per CONTRIBUTING.md this is an update to an existing entry rather than a new source entry, so it is expected to need maintainer review rather than the automated fast path. No other path is touched.

Install availability

grloper/dsh-deep-research — The 1024 Store installs plugins from npm only. Until dsh-deep-research (with its dsh.bundle declaration) is published to npm, this plugin is listed browse-only — visitors see the repository link but no install command. The catalog detects a newly published package automatically; no follow-up pull request is needed.

This pull request modifies or removes existing catalog entries, so it will not be merged automatically. A maintainer will review the change set and merge it manually.
