* Automate Grok Bot releases
* Refresh Grok Bot to apt 0.66.0 and harden upstream.sh
Bump both architectures to Cursor apt 0.66.0 with matching SHA256s,
introduce a versioned _pool URL helper, and filter Packages stanzas by
Package: grok-bot so sync stays correct if the index grows.
* grok-bot: bump to 0.68.1, drop manual hold, validate pool filename
Bump both architectures to Cursor apt 0.68.1 with the SHA256s from the
amd64/arm64 Packages indexes (verified against the downloaded debs).
Drop grok-bot from the manual holds list in docs/upstream-sources.md and
have upstream.sh check that the newest stanza's Filename is the versioned
pool path the PKGBUILD downloads from. Both additions come from #848.
Package the official Grok Bot Linux .deb (internal name: sand) for Arch.
Wraps /opt/Grok Bot/sand with a Wayland launcher and grok-bot desktop entry.
Linux has no latest feed; update-pkgver.sh resolves version+commit from the
darwin-arm64 sand feed and HEAD-checks the Linux deb before pinning.
