```
google_ai: Add Gemini 3.8 Flash (#63643)

# Objective

Add Gemini 3.8 Flash to Zed's built-in Google AI provider so it can be
selected from the model dropdown.

  ## Solution

Register `gemini-3.8-flash` with its 1 million token context window, 64k
output limit, and Low, Medium, and High thinking levels. Medium is the
default, and Low is used when thinking is disabled because the model
rejects Minimal.

Add tests covering the model metadata, serialization, token limits,
thinking levels, and disabled-thinking behavior.

  ## Testing

  Tested on Windows using Rust 1.98 GNU:

  - `cargo test -p google_ai` — 23 passed
  - `cargo fmt --all --check`
- `cargo +stable-x86_64-pc-windows-gnu clippy -p google_ai --release
--all-targets --all-features -- --deny warnings`

Reviewers can run `cargo test -p google_ai`. The pinned MSVC toolchain
was not tested locally because `link.exe` was unavailable.
