basecamp: bump flake input to github:basecamp/basecamp-cli/v0.8.0-rc.1.
The rc.1 tag ships a stale nix/package.nix whose vendorHash does not
match the tagged go.sum (buildGoModule FOD fails) and whose `version`
was not bumped (still reads 0.7.2). Override both on the pass-through so
the input builds and reports 0.8.0-rc.1. Drop the override back to a
plain pass-through once upstream fixes package.nix for the 0.8.0 final.
vibetyper: 1.4.0 -> 1.4.1 with refreshed AppImage sha256.
- vibetyper/msty-studio: unversioned AppImage URLs → HEAD/Last-Modified
check via custom update.sh, refreshes sha256 when upstream binary changes
- zellij-ps: switch to branch-tracking (master tip via Gitea API) since
helper-scripts repo has no tags
- all three expose passthru.updateScript so the existing CI workflow
discovers them via is_custom_update_script
