Release AntigravityRouter v0.1.18 · zsecducna/AntigravityRouter

What changed

Added per-model enable/disable controls in the Models tab.
Disabled provider models are removed from Antigravity's injected model catalog after relaunch.
Disabling a model now asks for confirmation before relaunching Antigravity.

Disabled model IDs are normalized before being saved.
If all provider models are disabled, stale provider aliases are cleared during catalog refresh.
Failed provider model fetches still preserve the previous working aliases.
