revert(desktop): remove the BETA gate — ship Hermes Cloud selector by default

Reverts the beta gating from 34d7d3f. The Hermes Cloud ModeCard in
Settings → Gateway now renders unconditionally alongside Local and Remote;
no BETA env var is consulted.

Not a clean `git revert`: commit 1b54d38 (the org-persist / stale-closure
fix) landed after the beta commit and edited the same useState block in
gateway-settings.tsx, so the revert conflicted there. Resolved by keeping
1b54d38's cloudOrgRef/setCloudOrg wrapper and dropping only the
cloudBetaEnabled state + its betaEnabled() useEffect. Everything else
(the sm:grid-cols-3 grid, the unconditional ModeCard, main.cjs/preload.cjs/
global.d.ts beta IPC) reverted automatically.

- main.cjs: drop betaFeaturesEnabled() + hermes☁️beta-enabled IPC
- preload.cjs / global.d.ts: drop the cloud.betaEnabled() bridge + type
- gateway-settings.tsx: drop the beta fetch/state; ModeCard renders
  unconditionally; grid back to sm:grid-cols-3

No test referenced the flag, so no test fallout. tsc clean; eslint clean on
all touched files.
