Each service its own version: ipx, ipx-directory, the page (#207)

The workspace stops holding one version. ipx keeps 0.12.1-dev and its vX.Y.Z tags; the directory
starts at 0.1.0-dev, tagged directory-vX.Y.Z, and the page at 0.1.0-dev in package.json, tagged
web-vX.Y.Z, which web/build.mjs gives the script for the logo's tooltip beside ipx's. crates/feed
is a library, not released. CLAUDE.md's release steps are for one service at a time.
