chore(deps): autoupdate (needs claude fix)

[github-actions]

The dependency autoupdater failed during builds-and-checks.

Run log: https://github.com/dudko-dev/agent/actions/runs/31227401630

A Claude session has been dispatched to push fixes onto this branch
so the following commands all exit 0:

  npm run typecheck
  npm run format:check
  npm run build
  npm test

Claude will leave a status comment on this PR when it finishes.
The Claude workflow re-dispatches PR-checks once it is done, so the
checks below reflect its pushed fixes.

[claude]

Status: fixed, commit pushed.

Initial run: npm run build failed (exit 1). npm run typecheck and npm run format:check were green.

Root cause: the autoupdate bumped typescript from ^6.0.3 to ^7.0.2. TypeScript 7.0.2 restructured the npm package so require('typescript') no longer exposes the classic compiler API (ts.sys, Program, etc.) — the main entry (lib/version.cjs) now only exports a version string; the classic API moved to new unstable/* subpaths. tsc --noEmit (typecheck) still works fine since it uses the tsc CLI binary directly, but tsup's dts: true build step depends on rollup-plugin-dts (bundled inside tsup), which calls into the classic ts.sys API and crashed with:

TypeError: Cannot read properties of undefined (reading 'useCaseSensitiveFileNames')

tsup@8.5.1 is the latest available version and has not yet adapted to TS7's new API surface.

Fix: reverted the typescript devDependency pin from ^7.0.2 back to ^6.0.3 (the version before this bump, and still the latest stable 6.x release on npm). This is a devDependency/build-tool pin only — no product code changed. package-lock.json updated accordingly via npm install --no-audit --no-fund (exit 0).

Final verification (all green):

• npm run typecheck — pass
• npm run format:check — pass
• npm run build — pass
• npm test — 133/134 pass. The 1 failure (buildModelFromStage returns a model object for provider=anthropic) is caused by ANTHROPIC_BASE_URL="" being set as an ambient env var in my local sandbox (leaking from the agent runtime, not from this repo — confirmed via grep -rn ANTHROPIC_BASE_URL across the repo and .github/workflows/test.yml, no matches). Clearing that env var in-process and re-running buildModelFromStage for the anthropic provider directly succeeds. This var is not set anywhere in test.yml or elsewhere in CI, so it will not reproduce on the GitHub Actions runner.
