use uv run --no-sync in pre-commit commands

[masenf]

allow pre-commit to work whether you have activated the virtualenv or not

[greptile-apps]

Greptile Summary

This PR updates .pre-commit-config.yaml to invoke every hook via uv run --no-sync instead of calling tools directly, so pre-commit works correctly whether or not the project virtualenv is activated.

• All five hook entries (ruff format, ruff check, codespell, python scripts/make_pyi.py, pyright) are prefixed with uv run --no-sync, delegating Python/tool resolution to uv without triggering a dependency sync on each run.
• The make_pyi hook also changes its invocation from python3 to python; under uv run this is handled by uv's Python resolver and is safe.

Confidence Score: 5/5

This PR is safe to merge — it makes a narrow, mechanical change to pre-commit hook invocations with no logic or runtime code affected.

The change only touches the pre-commit config, adding uv run --no-sync in front of each tool invocation. The --no-sync flag correctly skips dependency syncing (keeping hook startup fast), and uv's Python resolver handles the python vs python3 rename in the make_pyi hook cleanly. There are no behavioural regressions expected.

No files require special attention.

Filename	Overview
.pre-commit-config.yaml	All five hook entry-points prefixed with uv run --no-sync so pre-commit works with or without an activated virtualenv; python3 → python in the make_pyi hook.
