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.
