- Add cursor/filename.go for multi-account credential file naming
- Include auth.ID in session and checkpoint keys for per-account isolation
- Record authID in cursorSession, validate on resume to prevent cross-account access
- Management API /cursor-auth-url supports ?label= for creating named accounts
- Leverages existing conductor round-robin + failover framework

- Capture conversation_checkpoint_update from Cursor server (was ignored)
- Store checkpoint per conversationId, replay as conversation_state on next request
- Use protowire to embed raw checkpoint bytes directly (no deserialization)
- Extract session_id from Claude Code metadata for stable conversationId across resume
- Flatten conversation history into userText as fallback when no checkpoint available
- Use conversationId as session key for reliable tool call resume
- Add checkpoint TTL cleanup (30min)

- Rewrite tool call mechanism from interrupt-resume to inline-wait mode:
processH2SessionFrames no longer exits on mcpArgs; instead blocks on
toolResultCh while continuing to handle KV/heartbeat messages, then
sends MCP result and continues processing text in the same goroutine.
Fixes the issue where server stopped generating text after resume.
- Add switchable output channel (outMu/currentOut) so first HTTP response
closes after tool_calls+[DONE], and resumed text goes to a new channel
returned by resumeWithToolResults. Reset streamParam on switch so
Translator produces fresh message_start/content_block_start events.
- Implement send-side H2 flow control: track server's initial window size
and WINDOW_UPDATE increments; Write() blocks when window exhausted.
Fixes RST_STREAM FLOW_CONTROL_ERROR on large requests (178KB+).
- Decode new InteractionUpdate fields: TurnEndedUpdate (field 14) as
stream termination signal, HeartbeatUpdate (field 13) silently ignored,
TokenDeltaUpdate (field 8) for token usage tracking.
- Include token usage in final stop chunk (prompt_tokens estimated from
payload size, completion_tokens from accumulated TokenDeltaUpdate deltas)
so Claude CLI status bar shows non-zero token counts.
