* fix: stabilize multimodal image compatibility across OpenCode flows
Advertise vision-capable metadata in /v1/models and make model matching deterministic so OpenCode does not downgrade image support or route 4.6 models incorrectly. Expand request translation to accept OpenCode/OpenAI attachment shapes, sanitize [Image N] placeholders safely, keep image-only follow-up turns non-empty, and improve token accounting so base64 image bytes no longer inflate prompt token usage and trigger premature compaction.
* fix: deduplicate thinking streams and trim injected prompt noise
* fix: align /v1/messages thinking blocks and message_start usage
* fix: reduce repetitive thinking across tool turns
Select a single reasoning stream source, prevent chunk replay, and preserve structured tool-loop context so the model keeps continuity instead of re-planning each turn.
* fix: unify token counting on existing API endpoints
Compute usage deterministically on /v1/messages and /v1/chat/completions even when upstream omits tokenUsage.
- remove roo-only token path and keep behavior on existing endpoints
- add proxy/token_estimator.go with shared Claude/OpenAI estimators (input/system/messages/tools + output/thinking/tool calls)
- wire stream/non-stream handlers to use estimator-derived input/output usage
- update /v1/messages/count_tokens to reuse the same estimator
- keep robust upstream usage parsing/normalization in proxy/kiro.go while dropping parser-level estimate fallback
Why: direct upstream tests show metering/context events frequently arrive without tokenUsage in this environment; this made usage zero or inconsistent. Local deterministic accounting keeps reported usage stable and explicit.
- Add claude-sonnet-4.6 (dot and dash variants) to modelMap in translator.go
- Add claude-sonnet-4.6 and claude-opus-4.6 (plus -thinking variants) to the
static fallback model list in handler.go
- Realign existing opus-4.6 entries for consistency
- Multi-account pool with round-robin load balancing
- Auto token refresh for IAM IdC and Social auth
- Streaming support (SSE)
- Web admin panel with account management
- Docker support with GitHub Actions CI/CD
- Machine ID management per account
- Usage tracking (requests, tokens, credits)
