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/35411128248

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]

Autoupdate fix applied.

• Failing command initially: `npm run build` (typecheck and format:check were already green on first run).
• Root cause: the autoupdate bumped `typescript` from `^6.0.3` to `^7.0.2` (the new native-compiler major). `tsup`'s bundled `rollup-plugin-dts` reads TS-internal APIs whose shape changed in TS7, so the DTS build step crashed with `TypeError: Cannot read properties of undefined (reading 'useCaseSensitiveFileNames')` before emitting anything. tsup 8.5.1 is already the latest release and doesn't support TS7 yet, so there's no forward fix available upstream today.
• Change made: pinned `typescript` back to `^6.0.3` in `package.json` (compatibility shim only, no product logic touched) and re-ran `npm install --no-audit --no-fund` to update the lockfile.
• Verified green after fix: `npm run typecheck`, `npm run format:check`, `npm run build`, `npm test` (172 tests, 171 pass, 1 skipped — the live-model suite, expected without `AGENT_LIVE_MODEL_URL`) — all exit 0.
• Pushed: commit `8d45772` on `chore/autoupdate-35411128248`.
