Add new utility function to check if URLs end with trailing '#' character
Includes comprehensive test cases covering various URL patterns and edge cases
* fix(api): check whether to auto append api version or not when formatting api host
- extract api version to variable in GeminiAPIClient for consistency
- simplify getBaseURL in OpenAIBaseClient by removing formatApiHost
- modify provider api host formatting to respect trailing #
- add tests for url parsing with trailing # characters
* fix: update provider config tests for new isWithTrailingSharp function
- Add isWithTrailingSharp to vi.mock in providerConfig tests

* fix(anthropic): prevent duplicate api version in base url
The Anthropic SDK automatically appends /v1 to endpoints, so we need to avoid duplication by removing the version from baseURL and explicitly setting the path in listModels

* fix(anthropic): prevent duplicate /v1 in API endpoints
Anthropic SDK automatically appends /v1 to endpoints, so we should not add it in our formatting. This change ensures URLs are correctly formatted without duplicate path segments.
* fix(anthropic): strip /v1 suffix in getSdkClient to prevent duplicate in models endpoint
The issue was:
- AI SDK (for chat) needs baseURL with /v1 suffix
- Anthropic SDK (for listModels) automatically appends /v1 to all endpoints
Solution:
- Keep /v1 in formatProviderApiHost for AI SDK compatibility
- Strip /v1 in getSdkClient before passing to Anthropic SDK
- This ensures chat works correctly while preventing /v1/v1/models duplication

* fix(anthropic): correct preview URL to match actual request behavior
The preview now correctly shows:
- Input: https://api.siliconflow.cn/v2
- Preview: https://api.siliconflow.cn/v2/messages (was incorrectly showing /v2/v1/messages)
- Actual: https://api.siliconflow.cn/v2/messages
This matches the actual behavior where getSdkClient strips /v1 suffix before
passing to Anthropic SDK, which then appends /v1/messages.

* fix(anthropic): strip all API version suffixes, not just /v1
The Anthropic SDK always appends /v1 to endpoints, regardless of the baseURL.
Previously we only stripped /v1 suffix, causing issues with custom versions like /v2.
Now we strip all version suffixes (/v1, /v2, /v1beta, etc.) before passing to Anthropic SDK.
Examples:
- Input: https://api.siliconflow.cn/v2/
- After strip: https://api.siliconflow.cn
- Actual request: https://api.siliconflow.cn/v1/messages✅🤖 Generated with [Claude Code](https://claude.com/claude-code)

* fix(anthropic): correct preview to show AI SDK behavior, not Anthropic SDK
The preview was showing the wrong URL because it was reflecting Anthropic SDK behavior
(which strips versions and uses /v1), but checkApi and chat use AI SDK which preserves
the user's version path.
Now preview correctly shows:
- Input: https://api.siliconflow.cn/v2/
- AI SDK (checkApi/chat): https://api.siliconflow.cn/v2/messages✅
- Preview: https://api.siliconflow.cn/v2/messages✅
Note: Anthropic SDK (for listModels) still strips versions to use /v1/models,
but this is not shown in preview since it's a different code path.

* refactor(checkApi): remove unnecessary legacy fallback
The legacy fallback logic in checkApi was:
1. Complex and hard to maintain
2. Never actually triggered in practice for Modern SDK supported providers
3. Could cause duplicate API requests
Since Modern AI SDK now handles all major providers correctly,
we can simplify by directly throwing errors instead of falling back.
This also removes unused imports: AiProvider and CompletionsParams.

* fix(anthropic): restore version stripping in getSdkClient for Anthropic SDK
The Anthropic SDK (used for listModels) always appends /v1 to endpoints,
so we need to strip version suffixes from baseURL to avoid duplication.
This only affects Anthropic SDK operations (like listModels).
AI SDK operations (chat/checkApi) use provider.apiHost directly via
providerToAiSdkConfig, which preserves the user's version path.
Examples:
- AI SDK (chat): https://api.siliconflow.cn/v1 -> /v1/messages ✅
- Anthropic SDK (models): https://api.siliconflow.cn/v1 -> strip v1 -> /v1/models ✅🤖 Generated with [Claude Code](https://claude.com/claude-code)

* fix(anthropic): ensure AI SDK gets /v1 in baseURL, strip for Anthropic SDK
The correct behavior is:
1. formatProviderApiHost: Add /v1 to apiHost (for AI SDK compatibility)
2. AI SDK (chat/checkApi): Use apiHost with /v1 -> /v1/messages ✅
3. Anthropic SDK (listModels): Strip /v1 from baseURL -> SDK adds /v1/models ✅
4. Preview: Show AI SDK behavior (main use case) -> /v1/messages ✅
Examples:
- Input: https://api.siliconflow.cn
- Formatted: https://api.siliconflow.cn/v1 (added by formatApiHost)
- AI SDK: https://api.siliconflow.cn/v1/messages✅
- Anthropic SDK: https://api.siliconflow.cn (stripped) + /v1/models ✅
