vips 0.1.0

# Publish `vips` to crates.io and create a GitHub Release.
#
# Triggers:
#   - push of a version tag (vX.Y.Z or vX.Y.Z-pre)
#   - manual `workflow_dispatch` with a `tag` input (e.g. v0.1.0)
#
# Required repository secret:
#   CRATES_IO_TOKEN — crates.io API token with publish rights for crate `vips`
#
# Release order: publish vips-sys first, then this repo.
