Global standards require ty check for static type analysis. Currently not configured.

## Checklist
- [ ] Add ty to dev dependencies
- [ ] Configure ty rules in pyproject.toml
- [ ] Add ty check step to CI workflow
- [ ] Fix any type errors surfaced
Align repo config with global development standards - Add missing tsconfig strictness flags (noUncheckedIndexedAccess, exactOptionalPropertyTypes, noImplicitOverride, noPropertyAccessFromIndexSignature) and fix all resulting type errors - Replace ESLint/Prettier with oxlint 1.48.0 and oxfmt 0.33.0 - Pin all frontend and backend dependencies to exact versions - Pin GitHub Actions to SHA hashes with persist-credentials: false - Fix CI Python version mismatch (3.12 -> 3.14) and ruff target-version - Add vitest 4.0.18 with jsdom environment for frontend testing - Add ty 0.0.17 for Python type checking (non-blocking in CI) - Add actionlint and zizmor CI job for workflow linting and security audit - Add Dependabot config for npm, pip, and github-actions - Update CLAUDE.md and pre-commit hooks to reflect new tooling - Ignore Claude Code sandbox artifacts in gitignore Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> 2026-02-16 20:39:41 +01:00			`---`
