fix(server): bound resource usage for 3.1.2 (gijzelaerr#811)

chore(ci): fix deprecation warnings and update OS matrix

- Fix setuptools deprecation: use PEP 639 string license format
  (`license = "MIT"`) instead of table form (`license = {text = "MIT"}`)
- Disable uv cache in test-published-package jobs (no checkout, so
  cache-dependency-glob matches nothing and warns)
- Add ubuntu-26.04 to test matrix
- Add macos-15, windows-2025, ubuntu-26.04 to publish test matrix
