quecto-agent v0.1.0

First official release of quecto-agent — the coding agent built on the quecto core.

Highlights

• Full coding-agent loop: tool use, editing under approval, sandbox denylist, verification gates
• Session persistence: resume, undo, diff
• Manifest "flavors" with trust-on-first-use
• Interactive chat REPL (crossterm event loop, bracketed paste, Markdown + Mermaid rendering via merman)
• Reasoning controls (/reasoning), session-scoped and persisted across resume
• Multi-provider support: OpenAI-compatible and native Anthropic Claude Messages API (--provider anthropic), with reasoning mapped to thinking.budget_tokens
• Multimodal image input support (--image)
• Background process management and concurrent subagent delegation (spawn_subagent, monitor_subagents, cancel_subagent, up to 8 concurrent)
• Project-local .qkb Markdown notes
• OpenTelemetry tracing (otel feature flag) across run loops, steps, tool dispatch, and completions
• Native evaluation harness (quecto-eval) with SQLite storage and pluggable graders (script, telemetry, LLM rubric)

• UAT: 41 black-box scenarios, 34 pass / 7 minor polish partials, 0 failures, 0 blocking defects (see docs/UAT-report.md)
