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

[ryoppippi]

Refactor CI and release workflows to use just commands for consistency with local development workflow.

Changes

• CI now uses just install, just lint, just mypy, just test
• Release workflow now uses just update-version, just build, just publish
• justfile install command accepts variable extras arguments
• Added update-version, build, and publish commands to justfile
• Removes obsolete Python 3.9 special case for server.py exclusion (file was removed in bcb12b4)

Pull request overview

This PR refactors the CI workflow to use just commands instead of direct uv and mypy invocations, creating better consistency between CI and local development workflows. The changes simplify the CI configuration and remove obsolete Python version-specific workarounds.

Key changes:

• Replaced direct uv and tool commands with corresponding just commands (just install, just lint, just mypy, just test)
• Modified the install command in justfile to accept variable extras arguments for flexibility
• Removed Python 3.9 special case for server.py exclusion (file no longer exists)

The install command now requires explicit arguments, which breaks backwards compatibility. When called without arguments (e.g., just install), it will run uv sync with no extras, whereas previously it would install all extras.

Consider providing a default value to maintain backwards compatibility:

install extras="--all-extras":
	uv sync {{ extras }}

This allows the CI to override with different extras while maintaining sensible defaults for local development.

Suggested change

	install *extras:
	install extras="--all-extras":
