- converter: replace rough overhead formula (tools*70+350) with actual
estimateTokens on built few-shot messages + Cursor hidden overhead
(1300 base + perTool by schema_mode); remove 16000 output reservation
- cursor-client: sendCursorRequestFull now returns {text, usage?} to
capture real Cursor inputTokens/outputTokens from messageMetadata
- handler: add estimateCursorReqTokens() and [TokenDiff] log to compare
tiktoken estimate vs actual Cursor usage; fix non-stream retry paths
to update usage from retry result; skip auto-continue when response < 200 chars
- openai-handler: update 4 call sites for new sendCursorRequestFull return type
- config: raise default maxHistoryTokens from 130000 to 150000
- docs/config: remove incorrect 'tiktoken underestimates 10~20%' claim;
update overhead description and reference range to 130000~170000
The jscode/ directory was removed in v2.0.0 but the Dockerfile still
referenced it, causing docker compose build to fail.
