Update whois extension

[engeldlgado]

Description

This update improves the robustness and reliability of domain inputs in the WHOIS extension by introducing automatic URL sanitization and registered base domain extraction.

Key Changes:

• URL Sanitization: Paste raw URLs (e.g. https://ardehtulum.com/about or http://www.google.com/?query=1) straight from the browser address bar. The extension automatically strips the protocols (http://, https://, //), paths, query parameters, hashes, and the www. prefix.
• Registered Base Domain Extraction: Resolves an issue where querying a subdomain (like dash.cloudflare.com) caused the WHOIS query to fail (registry returned no records for the subdomain host), which was previously incorrectly parsed as the domain being Available for registration. Now, the extension intelligently extracts the registered base domain (e.g. dash.cloudflare.com -> cloudflare.com, sub.example.co.uk -> example.co.uk) to query WHOIS.
• Intact IP Resolution: Ensures valid IPv4 and IPv6 addresses are left untouched so they continue to resolve IP geolocation info accurately.

Why:

• UX Improvement: Users can copy-paste full URLs without having to manually edit or clean the text string.
• Reliability: Eliminates false-positive "Available" registration statuses when entering subdomains.

Screencast

(No visual changes to the UI itself, this is a logic improvement for parsing and sanitizing inputs to resolve domain whois data properly).

Checklist

• I read the extension guidelines
• I read the documentation about publishing
• I ran npm run build and tested this distribution build in Raycast
• I checked that files in the assets folder are used by the extension itself
• I checked that assets used by the README are placed outside of the metadata folder

Greptile Summary

This PR adds automatic URL sanitization and registered base domain extraction to the WHOIS extension, so users can paste raw browser URLs and subdomain inputs without triggering false-positive "Available" results. The previous generic commonSecondLevels approach has been replaced with a per-ccTLD ccSLDs map that correctly scopes SLD recognition.

• cleanInput strips protocols, paths, query strings, and the www. prefix using the native URL API, with a regex fallback for invalid URLs; IPv4 and IPv6 addresses are passed through untouched.
• getBaseDomain now consults ccSLDs before deciding between a 2-part or 3-part base domain, fixing prior false triggers on generic TLDs like .io or .me.
• The cl (Chile) entry in ccslds.ts is missing com, net, org, and mil — the most commonly registered SLDs under .cl — causing sub.example.com.cl to resolve to com.cl (the registry) and reproduce the false-positive "Available" bug the PR was designed to fix.

Confidence Score: 4/5

Safe to merge after fixing the incomplete cl ccSLD entry; all other new logic is well-tested and correct.

The cl entry in ccslds.ts is missing com, net, org, and mil — Chile's four most common registered SLDs. Without them, any subdomain under example.com.cl resolves to com.cl (the registry) rather than example.com.cl, causing the very false-positive "Available" WHOIS result this PR was designed to eliminate. The fix is a one-line change. Everything else — URL sanitization, ccSLD lookup logic, IPv4/IPv6 passthrough, and the anti-regression test suite — looks correct.

extensions/whois/src/utils/ccslds.ts — the cl entry needs com, net, org, and mil added before merge.

Important Files Changed

Filename	Overview
extensions/whois/src/utils/ccslds.ts	New ccTLD→SLD lookup table; the cl (Chile) entry is missing com, net, org, and mil — omissions that will route Chilean com.cl-style domains to the wrong WHOIS target.
extensions/whois/src/utils/index.ts	Adds cleanInput (URL stripping) and getBaseDomain (ccSLD-aware extraction); logic is sound for all tested cases.
extensions/whois/src/utils/index.test.ts	Comprehensive test suite covering URL sanitization, ccTLD SLD extraction, IPv4/IPv6 passthrough, and anti-regression cases. One stale comment references the removed commonSecondLevels variable.
extensions/whois/CHANGELOG.md	Changelog entry added for the new URL sanitization feature; content accurately reflects the changes.

### Issue 1 of 2
extensions/whois/src/utils/ccslds.ts:42
**Incomplete `cl` entry causes false-positive "Available" results for Chilean domains**

The `cl` (Chile) entry is missing `com`, `net`, `org`, and `mil` — the most widely used SLDs under `.cl`. Without them, `getBaseDomain` falls through to `parts.slice(-2)`, so a hostname like `sub.example.com.cl` resolves to `com.cl` (the registry) rather than `example.com.cl`. That WHOIS query either returns no record or registry info, producing exactly the false-positive "Available" status this PR was designed to fix.

```suggestion
  cl: new Set(["com", "net", "org", "gov", "gob", "edu", "mil"]),
```

### Issue 2 of 2
extensions/whois/src/utils/index.test.ts:134
The comment references `commonSecondLevels`, a variable that no longer exists — it was replaced by the `ccSLDs` map in `ccslds.ts`. Leaving the stale name will confuse future readers trying to trace the logic.

```suggestion
    // nic is not in ccSLDs, so sub.nic.google becomes nic.google
```
