feat(rebase): fork base on upstream v0.24.0 native architecture

- Rebased onto upstream/main (v0.24.0, full Rust native)
- Renamed package to agent-browser-stealth, version 0.24.0-fork.1
- Preserved fork-specific: abs alias, extensions/tab-group-cdp, .husky hooks
- Removed upstream-only: docs/, packages/dashboard, examples/, benchmarks/
- Simplified pnpm workspace to root-only
- Added [[bin]] section to keep binary name as "agent-browser"

Track 1 of native-stealth migration.
