fix(cli): expose off variant and add kilo gateway branch for GLM 5.2

GLM 5.2's reasoning variant mapping in ProviderTransform.variants had two
gaps introduced by PR #11555, which adapted upstream commit 22cc758b1a:

1. The @kilocode/kilo-gateway package was not covered, so the gateway fell
   through to the generic GLM binary toggle (instant/thinking) instead of
   GLM 5.2's native effort levels. This made the Kilo gateway show only two
   reasoning efforts while the cloud already pushes none/high/xhigh via
   REASONING_VARIANTS_NONE_HIGH_XHIGH.

2. The off (none) variant was dropped from the openrouter, openai-compatible,
   and anthropic branches, leaving each at only two variants and regressing
   custom openai-compatible providers (e.g. wafer) that previously exposed
   three.

This mirrors the cloud's three-variant definition (none/high/xhigh for the
gateway and openrouter; none/high/max for openai-compatible and anthropic,
matching z.ai native naming) and adds a kilo-gateway case so the computed
fallback matches the config the gateway pushes.

+Restore the off reasoning variant for GLM 5.2 and add the missing Kilo gateway branch so the effort selector shows all three supported levels (off/high/xhigh) instead of only two.
