fix(ci): use just commands in CI and release workflows (#57)

* chore(ci): use just commands instead of direct uv/mypy calls

Refactor CI workflow to use just commands for consistency with local
development workflow. This removes the obsolete server.py exclusion
from mypy (file was removed in bcb12b4) and makes justfile's install
command accept optional extras arguments.

Changes:
- CI now uses `just install`, `just lint`, `just mypy`, `just test`
- justfile install command accepts variable extras arguments
- Removes Python 3.9 special case for server.py exclusion

* chore(ci): use just commands in release workflow

Add update-version, build, and publish commands to justfile and update
release.yml to use them instead of direct uv calls.
