Note

The pull request "chore: Clean up lint and format script names" was created by @logaretm but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

Summary

Standardize lint/format script naming across the monorepo (53 files). Removes redundant/confusing scripts and makes naming consistent.

New root-level scripts

Script	Command	Purpose
check	run-s format:check lint	Read-only: format check + lint
fix	run-s format lint:fix	Write: format + lint fix
lint	oxlint . --type-aware	Lint only
lint:fix	oxlint . --fix --type-aware	Lint + fix only
format	oxfmt . --write	Format only
format:check	oxfmt . --check	Format check only

What changed

• lint now runs only oxlint (previously also ran oxfmt check)
• lint:fix replaces old fix for oxlint auto-fix
• New check runs both format:check + lint (replaces old lint behavior)
• New fix runs both format + lint:fix
• All oxlint commands consistently include OXLINT_TSGOLINT_DANGEROUSLY_SUPPRESS_PROGRAM_DIAGNOSTICS flag and --type-aware across root and all sub-packages
• Removes redundant scripts: 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
• yarn fix runs both format and lint fix at root level
