feat(browser): support Chrome channels and Chromium profiles

[ciltocruz]

Summary

Not everyone uses the stable Chrome release, so I thought it would be useful to support the other Chrome channels too.

• Adds Chrome Beta, Chrome Dev, Chrome Canary, Chrome for Testing, and Chromium as separate cookie-import sources.
• Keeps the existing Chrome and Microsoft Edge behavior.
• Supports the requested Windows profile roots, including discovery from WSL paths.

Related issue

Fixes #613

Affected areas

• Settings UI
• Documentation
• Other: browser profile discovery

Validation

• cargo fmt --all -- --check
• git diff --check b585d4887499c6b62d3a9ce7c22444e4bd283961...HEAD
• Focused Rust test could not run in this Linux environment: compilation stops in unrelated rust/src/providers/muse/local_usage/cache.rs because it uses Windows-only APIs.
• Thermo-nuclear code quality review completed; its duplicate browser registry finding was addressed.
• Contributor-reported Windows manual smoke test: the app showed Chrome and its profiles in the cookie-import browser list.

UI / tray proof

• Not applicable
• CUA Driver visual proof attached
• CUA Driver was unavailable from this WSL session; equivalent manual check: the contributor launched the Windows app and confirmed Chrome and its profiles appeared in the browser list.

Notes for reviewers

Please review that all six requested User Data roots map to distinct browser choices, while existing Chrome and Edge behavior remains unchanged.

Summary by CodeRabbit

• New Features
  • Browser import now detects Chrome Beta, Dev, Canary, and Chrome for Testing as separate browser options, with distinct profiles on supported Windows environments.
  • Chrome channel detection is supported in both native Windows and WSL environments.
• Documentation
  • Updated browser import guides to list Chrome Stable, Beta, Dev, Canary, Chrome for Testing, and Chromium alongside Edge, Brave, and Firefox.

📝 Walkthrough

Walkthrough

The change adds Chrome Beta, Dev, Canary, Chrome for Testing, and Chromium as distinct browser import sources. It resolves their profile paths, includes them in Windows browser detection, assigns import keys, and updates browser lists in the documentation.

Changes

Browser Import Sources

Layer / File(s)	Summary
Browser types and profile paths rust/src/browser/detection.rs	Adds four Chrome channel variants and maps them, Chrome Stable, and Chromium to Windows profile roots. Updates display names and adds tests for paths and browser type membership.
WSL browser detection rust/src/browser/wsl_paths.rs	Builds browser candidates from BrowserType::all() and profile paths. Candidate detection still checks directories for profiles. Tests cover the new Chrome channel and Chromium paths.
Import keys and browser lists apps/desktop-tauri/src-tauri/src/commands/browser_import.rs, README.md, docs/PROVIDERS.md	Maps each new Chrome channel variant to a distinct import key. Updates the README and provider documentation to list the supported browser choices.

Estimated code review effort: 3 (Moderate) | ~20 minutes
