VCO Release v2.3.50

Highlights

Added a router AI connectivity probe for the governance advice path, including a PowerShell gate, a runtime-neutral Python probe, structured status artifacts, and install-entry quick checks that distinguish local install completion from online governance readiness.
Hardened the LLM acceleration overlay’s optional-field handling so verification and fallback behavior stay stable when provider-side fields are missing or partially populated.
Expanded truthful host-adapter coverage across the current main branch: OpenClaw runtime-core flow was normalized and completed, OpenCode preview adapter/install surfaces were added, and Cursor/Windsurf preview support was aligned with the latest install/support matrices.
Consolidated the public install surface into a single entry, improved bilingual parity across install docs, and changed default Windows verification examples to powershell.exe so stock Windows environments are not blocked on pwsh.

Version-governance closure:
- pwsh -NoProfile -ExecutionPolicy Bypass -File ./scripts/verify/vibe-version-consistency-gate.ps1
- pwsh -NoProfile -ExecutionPolicy Bypass -File ./scripts/verify/vibe-version-packaging-gate.ps1
Router AI connectivity probe coverage:
- python3 -m py_compile scripts/verify/runtime_neutral/router_ai_connectivity_probe.py
- python3 -m pytest -q tests/runtime_neutral/test_bootstrap_doctor.py tests/runtime_neutral/test_router_ai_connectivity_probe.py
- pwsh -NoProfile -ExecutionPolicy Bypass -File ./scripts/verify/vibe-llm-acceleration-overlay-gate.ps1
Release-surface hygiene:
- git diff --check

Windows operators should use powershell.exe -NoProfile -ExecutionPolicy Bypass -File ... as the default verification entry unless PowerShell 7 (pwsh) is already installed.
The public install narrative is now centered on the single-entry docs under docs/install/one-click-install-release-copy*.md; older fragmented install entrypoints should not be treated as the primary onboarding surface.
OpenClaw, OpenCode, Cursor, and Windsurf remain truthful preview / runtime-core governed lanes according to the current support matrices; this release improves install truth, verification clarity, and adapter closure without claiming blanket host-native full closure.
