Usage records show a reasoning badge next to the model name for OpenAI and
Claude requests, but Gemini requests never got one. The extraction only read
the OpenAI/Claude shapes (`reasoning_effort`, `reasoning.effort`,
`output_config.effort`), while Gemini states its reasoning depth inside
`generationConfig.thinkingConfig` — so nothing was written to the usage
metadata and the list and detail views had no badge to render.
Read the Gemini shape too, as a fallback after the existing three so the
OpenAI and Claude paths are untouched:
- `thinkingLevel` / `thinking_level` wins when present, trimmed and
lowercased, with the protobuf enum prefix stripped so `THINKING_LEVEL_HIGH`
resolves like `high`.
- Otherwise `thinkingBudget` / `thinking_budget` goes through the existing
shared budget ladder, yielding the same `low|medium|high|xhigh` vocabulary
the badge already understands.
- Both camelCase and snake_case spellings are read, so a captured client body
and a converted provider body resolve to the same label.
- `includeThoughts` alone is a visibility flag, not a depth, and produces no
badge.
Two cases are handled explicitly rather than through the shared ladder:
- `thinkingBudget: 0` disables reasoning outright. The shared ladder maps
`0..=1664` to `low`, which would report an explicitly disabled request as a
shallow one, so it reports `none` instead.
- `THINKING_LEVEL_UNSPECIFIED` is the enum's "no explicit level" member, not a
depth; it is rejected rather than surfaced as an `unspecified` badge.
The frontend needs no change: `UsageModelDisplay` already renders the badge
whenever the fields are present, and keeps the `high -> xhigh` mapping format
when the requested and upstream efforts differ.
