…token generation Adds an optional `generateAuthToken` setting to `createVertexAnthropic` (both edge and node variants). When provided, the SDK calls this function instead of performing the default OAuth exchange. Default behavior is unchanged. Useful for tests, custom auth providers, and proxy/relay scenarios where the caller supplies the auth token directly.

…opic auth token generation (#14869) Backport of #14857 to \`release-v5.0\`. The v6 backport (#14861) is already merged. This brings the same change to v5 so the option is available across all live branches the AI Gateway depends on. ## Change Adds optional \`generateAuthToken\` setting on \`createVertexAnthropic\` (edge + node). When provided, the SDK uses it instead of the default OAuth exchange. Default behavior unchanged. \`\`\`ts createVertexAnthropic({ project: '...', location: '...', generateAuthToken: async () => myCustomToken(), }); \`\`\` ## Tests 29 tests across edge + node, including merge order, fresh-call semantics, error propagation, user-header override, and (node-only) null return. ## Risk Purely additive. No breaking changes.

Background
Today `createVertexAnthropic` (edge and node variants) unconditionally performs an OAuth exchange to mint a Bearer token before each request. Useful default — but there are real cases where you want to skip it:
Change
Adds an optional `generateAuthToken` setting to `GoogleVertexAnthropicProviderSettings` on both edge and node variants. When provided, the SDK calls it in place of the default OAuth flow. When omitted, behavior is identical to today.
Tests
Added one test per variant asserting that:
All existing anthropic tests still pass.
Risk
Purely additive. New optional field, default unchanged. No breaking changes.
