v0.1.0

First public release. Early alpha — it captures real agent harnesses end-to-end, but APIs, flags,
and the event schema will still change.

Added

• run command that wraps an agent harness, resolves a fork-tree context, and injects the spine
  into the child environment (HILOOP_*, OTEL_RESOURCE_ATTRIBUTES).
• stdio capture: tee the child's stdout, stderr, and stdin into normalized, fork-stamped JSONL
  events (--events-jsonl), with optional raw-observation preservation (--raw-jsonl).
• Embedded OTLP/HTTP receiver (--otlp) that captures the harness's own OpenTelemetry trace
  export; gen_ai.* / llm.* spans become llm events.
• Embedded cooperative MITM proxy (--proxy) that mints an ephemeral, child-scoped CA, decrypts
  the harness's HTTPS traffic, and emits fork-stamped net / llm events. Bodies stream into a
  content-addressed blob store (--blob-dir), so memory stays bounded for streaming/SSE responses.
• gRPC export (--export-grpc) to a hiloop telemetry gateway, with the API key read from
  HILOOP_API_KEY (never a flag). Composes with local JSONL durability logging.
• inspect command to summarize a captured events file by fork-tree node and to diff two branches.
• Prebuilt binaries for Linux (x86_64, arm64), macOS (Intel, Apple Silicon), and Windows (x86_64),
  attached to each GitHub Release with SHA-256 checksums.
