Add INS

[Montoya]

This closes #1503

---

Note

Low Risk
Registry-only metadata addition with a pinned checksum; no application or security-critical logic changes in this repo.

Overview
Adds npm:ins-snap-resolver to the MetaMask Snap registry so users can discover and install INS (Igra Name Service) for native .igra forward/reverse resolution in the recipient field (Ethereum mainnet and Igra L2).

The entry includes listing metadata (author, support, GitHub source) and pins version 0.1.0 with its bundle checksum, consistent with other name resolution snaps.

Hey team — thanks for merging #1504! Heads up: the post-merge workflow that triggers snaps-directory → republish-release.yml failed with a 403 — Resource not accessible by personal access token, with x-accepted-github-permissions: actions=write. Looks like the dispatch token is missing actions: write on snaps-directory, so the registry site never rebuilt and snaps.metamask.io/snap/npm/ins-snap-resolver is still 404. Could someone re-run the republish workflow (or fix the token perms)? The npm package (ins-snap-resolver@0.1.0) is published and ready. Thank you
