When a user sets an API key env var (e.g. DEEPSEEK_API_KEY) but doesn't explicitly configure a provider, dirge now auto-detects the matching provider instead of falling back to openrouter. Resolution order: CLI flag > config file > env var detection > openrouter Supports: DEEPSEEK_API_KEY, OPENAI_API_KEY, ANTHROPIC_API_KEY, GEMINI_API_KEY, GLM_API_KEY, OLLAMA_API_KEY, OPENROUTER_API_KEY Signed-off-by: allen-munsch <james.a.munsch@gmail.com>

The candidate list moves to a module-level `PROVIDER_AUTODETECT_ORDER` so tests reference the same source of truth — adds an isolation test (`auto_detect_each_provider_in_isolation`) that exercises every entry, guarding against accidental drops or reorders. 6 tests now pass deterministically (was 5 flaky). --------- Signed-off-by: allen-munsch <james.a.munsch@gmail.com> Co-authored-by: allen-munsch <james.a.munsch@gmail.com> Co-authored-by: Yogthos <yogthos@gmail.com>

Hey! Small quality-of-life improvement here.
The problem: Setting
DEEPSEEK_API_KEY(or any provider's API key) still required explicitly passing--provider deepseekor configuring it — otherwise dirge would fall back to openrouter. Felt a bit fiddly.What this does: If no provider is set via CLI flag,
DIRGE_PROVIDERenv var, or config file, dirge now checks for known API key environment variables and picks the matching provider automatically.Resolution order is:
--providerCLI flag /DIRGE_PROVIDERenv varproviderin config file*_API_KEYenv vars (new!)"openrouter"Supported vars:
DEEPSEEK_API_KEY,OPENAI_API_KEY,ANTHROPIC_API_KEY,GEMINI_API_KEY,GLM_API_KEY,OLLAMA_API_KEY,OPENROUTER_API_KEYChanges:
src/provider.rs— newauto_detect_provider()+ 5 unit testssrc/cli.rs—resolve_provider()calls auto-detect as a fallbackcargo clippy is clean (no new warnings), cargo fmt passes, and all 5 new tests + all 497 existing non-plugin tests pass.
Thanks for the great project!
edit: written with dirge and deepseek v4 pro i looked at the code changes, looked okay
