feat(providers): add ClinePass API-key provider (#5942)

Integrated into release/v3.8.44 — ClinePass API-key (BYOK) provider (port upstream 9router#2304, co-authored @adentdk). Validated locally: 16 clinepass tests green; fixed the APIKEY count 158→159 + translate-path golden snapshot (clinepass is a genuine new provider). Remaining UNSTABLE red is the pre-existing environmental setup-claude base-red (opencode-plugin dist not built in fast-path). Supersedes stub #5541.
