build: add oxlint and oxfmt tooling

[azizbecha]

Summary

Adds oxlint (linter) and oxfmt (formatter) to the monorepo, plus a committed .vscode folder so contributors get a consistent editor setup out of the box.

Changes

• Install oxlint and oxfmt as root dev dependencies
• .oxlintrc.json — correctness rules as warnings; ignores dist, legacy, and docs build output
• .oxfmtrc.json — formatter config with the same ignores
• .vscode/extensions.json — recommends the official oxc.oxc-vscode extension
• .vscode/settings.json — enables fix-on-save (source.fixAll.oxc), sets oxc as default formatter with format-on-save
• New root scripts: lint, lint:fix, format, format:check
• Removed .vscode from .gitignore (it was ignored, so the folder could never be committed)

Notes

• Type-aware linting is not enabled (requires the extra oxlint-tsgolint dependency) — can be a follow-up
• pnpm lint currently reports warnings on existing code (unused vars in handshakes/tests); nothing blocking
• pnpm format:check reports ~109 unformatted files — the repo-wide reformat is intentionally excluded to keep this diff reviewable, and can land as a separate PR

Test plan

• pnpm lint runs and respects the config
• pnpm format:check runs and respects the config

Poem

Hop, hop, through configs I go,
Oxc tools now start to glow,
Format on save, lint on cue,
.vscode unhidden, fresh and new,
A tidy warren, code so bright! 🐇✨
