v0.6.1

Removed

• FLAC 6.0 documentation. FLAC 6.x embeds Python 2.7, which cannot run
  itasca-mcp-bridge (Python >= 3.6), so its command docs were removed from
  the corpus and from the doc tools' version selectors. Requesting
  software="flac" with version="6.0" now returns an unsupported_version
  error stating the covered versions (FLAC: 7.0/9.0). PFC 6.0 is unaffected —
  it ships Python 3.6 and remains fully supported (PFC: 6.0/7.0/9.0). Shared
  _common docs no longer advertise versions outside the requesting engine's
  coverage.

Fixed

• Bridge (itasca-mcp-bridge 0.4.1): client disconnects no longer dump
  tracebacks into the engine GUI console. A dropped MCP client socket on
  Windows (WinError 10053, e.g. an SSE stream reconnecting) surfaced as a
  noisy ConnectionAbortedError traceback; the connection now deregisters
  quietly. Bridges pick this up automatically via self-upgrade on start.

Documentation

• README prerequisites and the agentic bootstrap guide now state per-engine
  minimum versions, with an engine-aware embedded-interpreter mapping; during
  bootstrap the agent stops early with a clear report when the interpreter
  resolves to python27 (FLAC 6.x) instead of failing at the pip step.
• README and bootstrap guide reframed as multi-engine (PFC → ITASCA), with
  client-native mcp add-style commands for manual setup and an explicit
  9.0+ engine recommendation.
