chore(packages): bump pins to current upstream releases

Refresh every package pin so the overlay stops carrying versions upstream
has moved past, and repair the pins where an automated bump had produced a
version that no longer resolves:

- graphify 0.9.61 -> 1.0.0 and back to tag tracking: the branch-tracking
  update script generated v0.9.77-unstable-<date> for a rev = "v${version}"
  src, a tag that never existed
- radar 1.13.1 -> 1.16.2 (upstream retagged its releases as k8s-ui-v*)
- llama-cpp b9645 -> b11439
- hipengine 0.5.0 -> 0.6.1, traycer 1.3.0 -> 1.4.2, freetoken 0.1.2 -> 0.1.3
- awg-tool 0.4.0, freebuff 0.2.19, kubernetes-mcp-server 0.0.67,
  marmel 0-unstable-2026-10-05, open-code-review 1.12.12,
  ds4 0-unstable-2026-09-20
- version-string normalisation for the branch-tracked packages already at
  their newest commit (g3, haivemind, shardr, skillsmcp)

Every changed src hash was re-fetched and verified. omniroute stays at
3.8.50: 3.8.51 changes its npm lockfile, so its npmDepsHash would have to
be recomputed before the bump is usable.
