Add Inception Labs Provider Support

Description

Add support for Inception Labs AI as a provider in Roo Code.

Motivation

Inception Labs offers competitive pricing and performance with their Mercury models:

• Mercury 2: Fast reasoning LLM for chat completions (128K context, $0.25/$0.75 per 1M tokens)
• Mercury Edit: Specialized for code editing tasks - FIM, apply-edit, next-edit (32K context)

Proposed Solution

Add provider configuration with:

• InceptionHandler extending OpenAICompatibleHandler
• Model definitions in packages/types/src/providers/inception.ts
• Full test coverage
• Settings integration

Reference

• https://docs.inceptionlabs.ai/get-started/models
• https://www.inceptionlabs.ai/blog/introducing-inception-api

Additional Context

Inception API is fully OpenAI-compatible, making integration straightforward.

I've analyzed this issue and here's my proposed implementation plan for adding Inception Labs provider support:

Proposed Implementation Plan

Since Inception API is OpenAI-compatible, this follows the same pattern as other simple providers like SambaNova. Here are the files that need to be created or modified:

1. New files to create

• packages/types/src/providers/inception.ts - Model definitions for Mercury 2 (128K context, $0.25/$0.75 per 1M tokens) and Mercury Edit (32K context, code editing specialist). Export InceptionModelId, inceptionDefaultModelId, and inceptionModels.

• src/api/providers/inception.ts - InceptionHandler extending BaseOpenAiCompatibleProvider, pointing to the Inception Labs API base URL (https://api.inceptionlabs.ai/v1), using options.inceptionApiKey.

• src/api/providers/__tests__/inception.spec.ts - Test coverage for the handler (base URL, API key, model selection, streaming).

• webview-ui/src/components/settings/providers/Inception.tsx - Settings UI component with API key input and model selector, following the SambaNova pattern.

2. Existing files to modify

• packages/types/src/providers/index.ts - Add export * from "./inception.js" and import/wire inceptionDefaultModelId in getProviderDefaultModelId().

• packages/types/src/provider-settings.ts - Add "inception" to providerNames, create inceptionSchema (extending apiModelIdProviderModelSchema with inceptionApiKey), add to discriminated union, flat schema, MODEL_ID_FIELD_BY_PROVIDER, and MODELS_BY_PROVIDER.

• packages/types/src/global-settings.ts - Add "inceptionApiKey" to SECRET_STATE_KEYS.

• src/api/providers/index.ts - Export InceptionHandler.

• src/api/index.ts - Import InceptionHandler and add case "inception" to the handler factory switch.

• src/shared/ProfileValidator.ts - Add "inception" to the case block that returns profile.apiModelId.

• webview-ui/src/components/settings/ApiOptions.tsx - Import and render <Inception> component for selectedProvider === "inception", add model config entry.

• Localization files - Add translation keys for the Inception Labs provider label and API key prompt (e.g., settings:providers.getInceptionApiKey).

Model Details (from Inception docs)

Model	Context	Max Output	Input Price	Output Price
Mercury 2	128K	TBD	$0.25/1M	$0.75/1M
Mercury Edit	32K	TBD	TBD	TBD

I'll confirm exact model IDs and pricing from the Inception Labs docs during implementation.

This approach mirrors how SambaNova and other OpenAI-compatible providers are integrated, keeping the implementation minimal and consistent.

Please mention @roomote in a comment saying that you approve this plan, and I'll proceed with the implementation.
