Users who run setup-uv earlier in their workflow get a redundant second
installation when this action unconditionally calls setup-uv again.

Detect uv on PATH before the install step and skip setup-uv if it's
already available. This keeps the action self-contained for standalone
use while avoiding duplicate installs in combined workflows.

Closes #7
