* ⚡ feat: Add Gemini 3.7 Flash Support

Adds first-class support for Google's Gemini 3.7 Flash (`gemini-3.7-flash`)
for both the Gemini API (AI Studio) and Google Cloud Gemini Enterprise Agent
Platform, following the Gemini 3.6 Flash integration (#14369).

- Context window (1,048,576) in googleModels; API + cache pricing in tx.ts.
- Model dropdown (config.ts) and GOOGLE_MODELS examples for both integrations.
- Register the model in the Flash-family handler so it inherits the existing
  strip of deprecated sampling params (temperature/topP/topK), rejected
  penalty params, and thinkingBudget, and defaults to `medium` thinking.
- Generalize that handler's enumerated table from a [id, level] tuple to a
  rule object, so a model can also declare thinking levels it rejects. Gemini
  3.7 Flash errors on `minimal` (which the Google endpoint offers in its
  thinkingLevel slider), so an explicit `minimal` is substituted with the
  nearest supported level, `low`. Explicit low/medium/high pass through
  unchanged.
- Apply Google's introductory pricing ($0.75 in / $3.75 out / $0.075 cached,
  per 1M) to Gemini 3.7 Flash and correct Gemini 3.6 Flash to the same rates.
  Both revert to $1.50 / $7.50 / $0.15 on 2027-01-01; noted at both call sites.

Resolves #14802

* 📝 docs: Match the House Style for Promotional Rate Comments

Align the Gemini 3.6/3.7 Flash introductory-pricing notes with the existing
Sonnet 5 convention in the same file: one comment per group, naming the models
and the exact values to restore, so the manual follow-up is unambiguous.

No rate changes.

* ⬆️ chore: Bump `@librechat/agents` to 3.4.7 for Gemini 3.7 Flash Prefill

Unblocks this PR. `NO_PREFILL_GEMINI_MODELS` is model-enumerated in the agents
SDK, so 3.4.6 does not know `gemini-3.7-flash` forbids a trailing `model`-role
turn — editing an assistant reply and resubmitting would reach Google as a
prefill and return HTTP 400 on a model this PR adds to the default list.

3.4.7 (danny-avila/agents#412, released via #413) adds it. Verified the
published tarball: `3.4.6...3.4.7` touches only
`dist/{cjs,esm}/llm/google/utils/common.*` — the prefill array and its comment.
`dist/types` is byte-identical, so there is no API surface change.

Raises the declared range in both workspaces alongside the lock. `^3.4.6`
already permitted 3.4.7, but the fix is required rather than merely compatible,
so the floor should say so.
