Reverts the 2.40→2.49 version spam from this session — every phase
commit was bumping the display version when the whole Search/Artists
unification project should really be a single release.
Changes:
- _SOULSYNC_BASE_VERSION back to 2.39
- All session-level version-info sections consolidated — the endpoint
response is back to the pre-session 2.39 shape
- helper.js WHATS_NEW entries for 2.40–2.49 collapsed into a single
'2.40' block with one bullet per phase, marked unreleased
- _getLatestWhatsNewVersion / _showOlderNotes filter out entries
whose version is higher than the current build, so the 2.40 block
won't fire the 'new' badge or appear in the What's New panel until
we actually flip the build version
- Picks up the artist-detail back-button fix from the previous turn
(falls back to browser history when the user reached the inline
detail from outside the Artists page)
When the unification project is done, a single commit that bumps
_SOULSYNC_BASE_VERSION to 2.40 will publish the whole folded entry.
- Pass source through artist, library, wishlist, and rehydration album-track fetches
- Preserve the resolved metadata source on cached discography and artist detail state
- Prevent 404s when opening artist-page album modals from non-Spotify sources
