fix: source uv environment after fresh installation in install.sh

After installing uv via the astral.sh installer, the current
shell's PATH is not updated, causing 'uv not found' errors.

Source the uv env script (or fall back to adding ~/.local/bin
to PATH) after installation so subsequent commands can find uv.

Fixes #1107
