Fixes Cursor agent token usage parsing for top-level camelCase, nested camelCase, and legacy nested snake_case result usage shapes. Includes tests for the locally verified nested camelCase stream-json output.
The current cursor-agent CLI no longer has a 'chat' subcommand. The
positional 'chat' argument was silently treated as prompt text, leaking
into the user message (e.g. 'chat <actual prompt>').
Remove 'chat' from buildCursorArgs so the generated argv matches the
current cursor-agent CLI interface.
Fixes#3077
* feat(agent): add Cursor Agent CLI runtime support
Add cursor-agent as a new agent backend, following the same pattern as
existing providers. The implementation spawns cursor-agent CLI with
stream-json output, parses JSONL events into the unified Message type,
and supports session resume, usage tracking, and auto-approval (--yolo).
Changes:
- server/pkg/agent/cursor.go: cursorBackend implementation
- server/pkg/agent/cursor_test.go: unit tests for args, parsing, errors
- server/pkg/agent/agent.go: register "cursor" in New() factory
- server/internal/daemon/config.go: probe cursor-agent in PATH
- server/internal/daemon/execenv/context.go: cursor skill discovery path
- server/internal/daemon/execenv/runtime_config.go: AGENTS.md injection
- packages/views/.../provider-logo.tsx: cursor logo in UI

* fix(agent): address PR review for cursor backend
1. Fix token usage double-counting: usage is now taken exclusively from
"result" events (session totals). Per-message usage in "assistant"
events is intentionally ignored. "step_finish" usage is only used as
fallback when no "result" usage is available.
2. Remove dead code: isCursorUnknownSessionError() and its regex were
defined but never called. Removed along with corresponding test.

* fix(agent): add missing CustomArgs, SystemPrompt, MaxTurns, and debug logging to cursor backend
- Add cursorBlockedArgs and filterCustomArgs support for safe custom arg passthrough
- Add --system-prompt and --max-turns flag support to buildCursorArgs
- Add debug logging of command args before execution (consistent with all other backends)
- Move stdout-close goroutine inside main goroutine (consistent with claude.go pattern)
- Add tests for SystemPrompt/MaxTurns and CustomArgs filtering

* chore: make daemon uses local profile & update Cursor logo to official brand
- Makefile: make daemon now runs 'daemon start --profile local' for local dev
- Replace Cursor runtime logo with official brand SVG (removed background rect)

* fix(agent): remove unsupported --system-prompt and --max-turns from cursor-agent
cursor-agent CLI does not support these flags. Instructions are already
injected via AGENTS.md and .cursor/skills/ files.

* fix(agent): prevent step_finish + result usage double-counting in cursor
Split usage accumulation into separate stepUsage and resultUsage maps.
After stream ends, use resultUsage if available (session totals from
result event), otherwise fall back to stepUsage (sum of step_finish).
This prevents 2x counting when result.usage already includes totals.
Added table-driven test covering: result-only, step_finish-only,
step_finish+result (no double count), and multi-model scenarios.
