chore: Clean up lint and format script names #19720

Summary

• Standardize lint/format script naming across the monorepo (53 files)
• lint now runs only oxlint (previously also ran oxfmt check)
• lint:fix replaces fix for oxlint auto-fix
• format / format:check unchanged (oxfmt write / check)
• New root-only check script runs both format:check + lint
• All oxlint commands now consistently include OXLINT_TSGOLINT_DANGEROUSLY_SUPPRESS_PROGRAM_DIAGNOSTICS flag and --type-aware across root and all sub-packages
• Removes redundant scripts: fix, fix:oxlint, fix:oxfmt, lint:oxfmt, lint:oxlint
• Updates CI workflow (build.yml) to use new script names

Test plan

• CI lint job passes with yarn lint instead of yarn lint:oxlint
• CI format check job passes (unchanged yarn format:check)
• yarn check runs both format check and lint at root level
