style: apply oxfmt baseline formatting across all source files (#25)

## Summary
- Run `oxfmt .` across the entire codebase to establish formatted baseline
- 299 files changed — mechanical formatting only, no logic changes
- Double quotes, semicolons, 2-space indent, trailing commas, 100 print width

Part 3/4 of [VA-851](https://linear.app/heygen/issue/VA-851/pre-migration-configure-eslint-prettier-and-conventional-commits)

## Test plan
- [x] `pnpm format:check` — all 426 files pass
- [x] `pnpm -r typecheck` — all packages pass
- [x] `pnpm build` — all packages build
- [x] All 348 tests pass
