v0.1.0 - first public release

A self-hosted, observable orchestrator for multi-agent workflows on
your repos. See CHANGELOG.md for the full release notes.

Highlights:
- Multi-agent fleet, three trigger kinds (labels, events, cron) plus
  reactive inter-agent dispatch with depth/fanout/dedup safety limits.
- Multi-backend: Claude Code, Codex, custom local LLM via the built-in
  Anthropic-OpenAI translation proxy.
- Three equal-power operator surfaces: REST API, MCP server (~45
  fleet-management tools), embedded Next.js dashboard.
- Durable SQLite event queue with crash-recovery replay; persisted
  trace transcripts (tool calls + thinking blocks); SSE streams for
  events, traces, memory.
- Two built-in prompt guardrails enabled by default:
  security (anti-injection) and mcp-tool-usage (positive direction
  for repo interactions, especially load-bearing for local models).
- Single Go binary, multi-stage Docker build, two named volumes.
