fix(ci): sync manifest version from tag before build (#49)

The release workflow was always building with the hardcoded version
from package.json (1.0.0), causing Chrome Web Store to reject uploads
because 1.0.0 equals the already-published 1.0 (trailing zeros ignored).

Added a step to extract the version from the git tag and update
package.json before the build, so the zip contains the correct version.
