0.3.43

[FoxsterDev]

• Hardened native Windows installation and launch paths: self-hosted refresh
  launchers, safe paths with spaces, predictable non-zero error propagation,
  Python 3.10+ gating, UTF-8 process handling, and client configs that point to
  the resolved launcher path.
• Improved cross-platform Unity discovery and readiness recovery, including
  extra Unity Hub installation locations, host-native recovery commands, and
  faster failure when interactive readiness cannot be achieved.
• Made bridge file IPC and request artifacts safer under lifecycle churn with
  atomic writes, torn-read resistance, process identity checks, subprocess
  timeouts, and editor-main-thread-safe runtime paths.
• Added end-to-end host regressions for Windows launchers, PowerShell setup,
  MCP stdio, installed delegate recovery, hostile code pages, and simulated
  file-IPC bridge behavior.
• Added public issue templates, contribution and conduct guidance, and an
  explicit independent-project notice.
