fix: route MiniMax compacting through Anthropic-compatible API (#1154)

* fix: route MiniMax through Anthropic-compatible API

Switch MiniMax provider setup away from the OpenAI-compatible shim and onto the Anthropic-compatible endpoint. Update env-only, provider flag, and saved profile paths to use ANTHROPIC_* while preserving legacy OPENAI_MODEL as a migration fallback.

Adjust MiniMax M2 context metadata so shared descriptors use the gateway-safe 196608 window and the direct MiniMax catalog overrides to the documented 204800 window. Extend runtime context lookup to anthropic-proxy routes so compact budgeting uses the direct provider metadata.

Update MiniMax client, provider profile, provider flag, context, and auto-compact tests for the Anthropic-compatible route and provider-specific compact limits.

* test: cover MiniMax provider manager paths

Update ProviderManager test fixtures so MiniMax uses the Anthropic-compatible endpoint instead of the old OpenAI-compatible /v1 endpoint.

Add coverage for the /provider add flow to assert MiniMax saves provider=minimax, endpoint https://api.minimax.io/anthropic, and displays the Anthropic-compatible API provider type.

Add edit-flow coverage to ensure existing MiniMax profiles remain on the Anthropic-compatible provider path and continue hiding OpenAI-only advanced fields.

* test: isolate MiniMax env-only coverage

Harden MiniMax client and compact tests against ambient CI provider env such as OPENAI_API_KEY, ANTHROPIC_BASE_URL, and provider-profile markers.

The compact budget test now explicitly clears competing provider flags before asserting direct MiniMax metadata, preventing CI-level OpenAI credentials from masking env-only MiniMax route detection.

* test: reset provider env inside MiniMax client cases

Make each env-only MiniMax client test clear competing provider flags, OpenAI/XAI keys, Anthropic env, and saved-profile markers before setting MINIMAX_API_KEY.

This keeps the Anthropic-compatible MiniMax route assertions independent of CI-level process env that can otherwise mask env-only provider detection in the full serial suite.

* fix: honor explicit MiniMax routing intent

Route MiniMax env-only requests by explicit MiniMax model/base intent even when generic OpenAI-compatible environment variables are present, while preserving non-MiniMax base URL conflicts.

Use the resolved MiniMax env-only path for Anthropic SDK key selection so stale provider classification or Bun module mocks cannot fall back to an Anthropic test key.

Harden MiniMax compact coverage against leaked env overrides and prior autoCompact module mocks, and cover the ambient OpenAI/XAI env regression.

* test: clean up compression autoCompact mocks

Restore Bun module mocks after compression test files so their deterministic autoCompact window does not leak into later compact tests in full-suite order.

Verified the MiniMax compact regression now passes after the compression suites and in the full local test log.

* test: avoid autoCompact module mocks in compression tests

Replace the compression suites' top-level Bun module mocks for autoCompact/config with real test config and env controls. This avoids Bun 1.3.11 leaking a mocked effective context window into the later MiniMax compact test in full-suite order.

Verified compression-before-compact and MiniMax focused suites pass locally.

* test: allow capped MiniMax compact reservation

CI enables the output-token slot-reservation cap, so MiniMax's direct 204,800 context can produce a 196,800 effective compact window instead of the uncapped 184,800. Keep the test focused on direct MiniMax context metadata while accepting either reservation state.

* fix: address MiniMax review findings

Treat env-only provider routes such as direct MiniMax as complete startup provider selections so saved profiles do not override explicit MINIMAX_API_KEY/ANTHROPIC_* env.

Stop advertising direct MiniMax benchmark support through the OpenAI-compatible benchmark path, and add regression coverage for the unsupported direct MiniMax benchmark env.

* fix: classify MiniMax profile startup correctly

Recognize MiniMax when /provider loads it through the Anthropic-compatible env shape using ANTHROPIC_BASE_URL, ANTHROPIC_MODEL, and ANTHROPIC_API_KEY.

Label MiniMax correctly on the startup screen and skip the Anthropic custom-key approval prompt when the resolved provider is not using the Anthropic account flow.

Add regressions for route metadata, legacy provider classification, account-flow bypass, and startup display for Anthropic-compatible MiniMax profiles.

* fix: include Anthropic key in provider secret source

Allow MiniMax profile redaction to include ANTHROPIC_API_KEY in the SecretValueSource type used by sanitizeProviderConfigValue.

This fixes the PR-specific TS2353 reported by review while keeping the MiniMax Anthropic-compatible key alias redacted alongside MINIMAX_API_KEY.

Validation: bun test --max-concurrency=1 src\utils\providerProfiles.test.ts src\utils\providerFlag.test.ts src\utils\model\providers.test.ts src\integrations\routeMetadata.test.ts; bun run typecheck still has existing repo-wide errors, with no providerProfile.ts matches.

* test: stabilize tool history compression smoke

Add a narrow compression-enabled override for tests so the compression suites do not depend on shared global config state from the full Bun runner.

Pass explicit effective context windows in direct compression tests and use catalog-backed models in shim compression tests to avoid env-capped tier drift.

Verified with focused compression tests, full bun test --max-concurrency=1, and bun run build.

* test: stabilize Orama corruption recovery assertion

Verify the quarantined corrupted Orama file from the actual persistence directory returned by getOramaPersistencePath, instead of assuming the config-dir projects root used by the full CI runner.

Verified with the failing KnowledgeGraph stress test, compression smoke suites, full bun test --max-concurrency=1, and bun run build.

* fix: refresh MiniMax compact branch

Merge upstream/main into fix/minimax-compact so PR #1154 is current with the target branch.

Also fix two branch-local FetchType test casts that surfaced during typecheck scanning of the MiniMax/xAI fallback tests.

Validation: bun test --max-concurrency=1 src/utils/providerProfiles.test.ts src/utils/providerFlag.test.ts src/utils/model/providers.test.ts src/integrations/routeMetadata.test.ts src/services/api/client.test.ts src/services/compact/autoCompact.test.ts src/utils/model/benchmark.test.ts; bun run build.
