Adds an optional path_suffix field that lets users override the API path
for OpenAI-compatible endpoints. When set, the suffix replaces the default
/v1/<path> pattern, enabling use with endpoints that don't accept /v1/
prefixes (e.g. /chat/completions instead of /v1/chat/completions).
Changes:
- ProviderConfigToml (config crate): path_suffix field
- ProviderConfig (tui crate): path_suffix field
- merge_provider_config: propagates path_suffix
- merge_project_provider_config: propagates path_suffix
- api_url: delegates to new api_url_with_suffix function
- api_url_with_suffix: uses suffix when present, skips /v1 versioning
- DeepSeekClient: reads path_suffix from config, passes to URL builder
- config.example.toml: documents the new option
- Tests for the new URL building behavior
Closes#2089
