fix(extension): resolve build error - fix file encoding and JSX config

- Fix escaped quotes in ThreadGeneratorPanel.tsx (root cause of build error)
- Update tsconfig.json to use jsx: react-jsx instead of preserve
- Upgrade Plasmo to v0.90.5 (latest version)
- Build now succeeds in 4.7s

Root Cause: ThreadGeneratorPanel.tsx had escaped quotes (\") instead of
normal quotes ("), causing SWC parser to fail with 'Unexpected token div' error.
This was a file encoding issue, not a Plasmo version issue.

Fixes #build-error
