test(providers): delete four hand-written test files the provider factories replace

[cunninghamcard-bit]

What

Removes the hand-written configuration, reasoning-map, transcription-stream and Node body-override test files before the provider factory migration. This branch follows provider-result-types and precedes upstream-samples in the stack split from #214. Its final diff only deletes test files; it does not change provider implementation or public types.

Before and after

Area	Before	After	Upstream reference
Configuration snapshots	Tests assert the existing registry construction and recorded configuration.	aimux-providers/tests/config_snapshot_test.rs is deleted.	@ai-sdk/openai/src/openai-provider.ts; factory changes follow on provider-factory-source.
Reasoning and request overrides	Tests assert Rust registry profiles and request-body overrides.	aimux-providers/tests/reasoning_map_test.rs is deleted.	Provider request conversion modules under @ai-sdk/*/src; vendor alignment follows later.
Transcription streaming	Tests exercise the Rust realtime WebSocket stream interface.	aimux-providers/tests/openai_transcription_stream_test.rs is deleted.	@ai-sdk/openai/src/transcription/openai-transcription-model.ts.
Node body overrides	Tests exercise the Node-to-Rust HTTP path and existing factory configuration.	bindings/node/__test__/body_overrides.test.ts is deleted.	@ai-sdk/openai/src/openai-provider.ts; binding migration follows on provider-factory-source.

Tests

The final diff deletes only the four hand-written files above: git diff --shortstat rfc-0036/provider-result-types rfc-0036/factory-test-removal reports 4 files changed and 1,594 deletions. The upstream-ported provider test files remain in this branch. They are absent again on upstream-samples, then restored and migrated to the factory API on provider-factory-source. Cassette replays are kept, and neither cassettes nor fixtures change in this pull request. No replacement hand-written tests are added.

Not in this pull request

• Provider factories and binding API migration belong to provider-factory-source, so production code can be reviewed separately from these deletions.
• Sample files belong to upstream-samples; this branch does not introduce replay payloads.
• The by-name entries in aimux_providers::provider used by FFI, Node and Python remain pending the maintainer's decision. Deleting configuration tests does not decide which construction entries remain public.

Stack refresh (2026-10-07)

Head 95ac2653 follows rfc-0036/provider-result-types at c16749d6. The stack includes master at 0b365b39 and the updated #203 (3e2d9fc7), #204 (b897cb21) and #213 (7c0933b1). Updated parents were merged into their children to preserve the existing public merge history; the PR base and Draft state are unchanged.

Verification

• Relative to the updated immediate base: 4 files changed, 1594 deletions(-).
• Rust formatting and workspace Clippy passed during this layer’s refresh. Final integration at local wire-format 415e37e1 passes cargo fmt --all -- --check, cargo clippy --workspace --all-targets -- -D warnings, and the provider boundary script.
• Full cargo test --workspace at final wire-format: 2,819 passed, 0 failed, 6 ignored, including doctests. The intermediate factory-source integration also passed 2,434 tests before the final obsolete Decision hook removal. These are integration results, not a claim that the full suite was rerun at every PR head.
• Generated TypeScript synchronization, Node build:typed, and web production build passed at the wire-format layer.

Not verified

No GitHub check runs are attached to this Draft stack head at the time of this update. Go, Java, Kotlin, Swift and Flutter bindings were not compiled locally in this refresh; Node npm test and Python pytest were not run. Live vendor calls and unported upstream cases remain outside this validation.
