Use uv tool run for pre-commit to avoid dependency declaration

[Copilot]

The Makefile runs uv run pre-commit, but pre-commit isn't in pyproject.toml dependencies, causing failures in fresh environments.

Changes

• Makefile: Replace uv run pre-commit with uv tool run pre-commit in install and check targets

This runs pre-commit in an isolated environment without requiring it as a project dependency.

# Before
@uv run pre-commit run -a

# After
@uv tool run pre-commit run -a
