chore(uv[cooldown]): Exempt ruff from release cooldown

why: uv's global `exclude-newer = "3 days"` supply-chain cooldown hides
ruff 0.16.0 (released 2026-07-23) from the resolver, so the version
floor in the next commit cannot resolve.

what:
- Add `ruff = false` to `[tool.uv.exclude-newer-package]`

Temporary. Revert before merge - the cooldown clears on its own and the
`ruff>=0.16` floor is what actually holds the version.
