release

Bump versions and tag plugins for release in the solopreneur multi-plugin marketplace. Detects which sub-plugins changed since their last tag, checks whether the root README is stale relative to those changes (offering one proposal at a time), asks the user for per-plugin patch/minor bumps, composes an outward CHANGELOG.md entry from the per-plugin diff (every release, user-reviewed), commits the bumps + changelog in a single commit, creates double-dash git tags, and pushes commit + tags atomically. Optionally creates one GitHub Release on solopreneur--v<new> for user-visible milestones (skip for routine bumps).
