chore(deps): autoupdate (needs claude fix)

[github-actions]

The dependency autoupdater failed during builds-and-checks.

Run log: https://github.com/dudko-dev/agent-web/actions/runs/32536911469

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.

Autoupdate fix-up: build was failing

• npm run build failed: the autoupdater's bump of typescript devDependency from ^5.6.0 to ^7.0.2 breaks tsup's bundled rollup-plugin-dts during the DTS build step (TypeError: Cannot read properties of undefined (reading 'useCaseSensitiveFileNames')). npm run typecheck itself was green under TS 7, but npm run build was not.
• npm run typecheck and npm run format:check were green on first run.
• Fix: pinned typescript back to ^5.9.3 (latest 5.x) in package.json/package-lock.json. This is a compatibility pin only — no product code changed, package version not bumped.
• Verified clean (rm -rf node_modules dist && npm ci) run of all four commands after the fix: typecheck ✅, format:check ✅, build ✅, test ✅ (96/96 passing).
• Pushed commit 54d70bc to chore/autoupdate-32536911469.
