hub v0.29.0: Day-0 artifact manifest — version dropdowns + auto-derived sha

Operator picks a version from a Gitea-populated dropdown; the hub reads that
version's sha256 from Gitea itself (files-metadata API, no artifact download) and
vouches it — no hand-copied checksums. New internal/gitea read-only client
(ListVersions + FileSHA256, unit-tested). Configuration UI: version <select>s +
read-only sha display; handleSetArtifacts derives the sha authoritatively and
refuses the save on a Gitea lookup failure. Degrades to manual text entry without
registry creds. go build/vet/test clean.

// Package gitea is a minimal read-only client for the Gitea generic-package API. It lets the hub
// discover which artifact versions currently exist (olders get pruned) and read each file's sha256
// WITHOUT downloading the artifact — so the operator picks a version in the UI and the hub derives and
// vouches the checksum itself, instead of the operator pasting a 64-hex sha by hand.
