fix(release): move version comment above the version line

The auto-release workflow uses sed with the regex
\`^version = ".*"\$\` to bump the version. An inline trailing
comment broke the \`\$\` anchor, causing sed to silently no-op.

Without the version bump, the workflow would tag v0.4.0 again,
fail to create a duplicate GitHub release, and \`uv publish\`
would error because 0.4.0 already exists on PyPI.

Verified by simulating the sed against the file for patch,
minor, and major bumps.
