chore(packages): bump packages to latest upstream versions

Update every package to its newest upstream release/commit:
- aionui 2.1.50 -> 2.2.2
- awg-tool 0.2.2 -> 0.3.0
- ds4 -> 0-unstable-2026-09-12
- freebuff 0.0.142 -> 0.0.174
- graphify 0.9.35 -> 0.9.61
- hipengine 0.3.0 -> 0.5.0
- mcp-gateway 3.4.0 -> 3.5.1
- omniroute 3.8.49 -> 3.8.50
- radar 1.9.1 -> 1.13.1
- relay-free-llm -> 0-unstable-2026-08-31
- traycer 1.1.10 -> 1.3.0

Refresh all source/dependency hashes (src, cargoHash, vendorHash,
npmDepsHash, bun FODs) and keep treefmt clean.

Packaging fixes required by the bumps:
- graphify: relax the setuptools>=83 build-backend pin (nixpkgs ships
  setuptools 80.x; the PEP 639 metadata needs only >=77).
- hipengine: add a llguidance 1.8.0 override (nixpkgs ships 1.7.x).
- omniroute: use npmDepsFetcherVersion 2; the v1 fetcher drops packages
  whose lockfile entries lack resolved URLs, breaking npm's cache check.
- radar: fix a frontend npmDepsHash/vendorHash swap from nix-update.

Packages already at latest are untouched: container-use, desloppify,
freetoken, kubernetes-mcp-server, loop, nftables-analyzer,
nftablesbuilder, stakpak, haivemind, skillsmcp. llama-cpp stays pinned
at b9645 and is tracked separately (manual HIP flag re-validation).
