v2.3.6 - Editor bridge and packaging fixes

Highlights

• ships the fixes from PR #48 for issues #46 and #47
• surfaces duplicate bridge startup failures such as EADDRINUSE in editor status instead of looking like silent disconnects
• hardens modify_script payload handling for Windows escaping and bridge-backed Vector2 property coercion
• avoids runtime addon socket errors during shutdown polling
• documents the typed JSON Vector2 contract and the MCP client reconnect caveat for dynamic tool groups
• makes release verification more robust by tolerating npm pack --json output when npm prepends prepare/build logs

Verification

• npm run ci
• npm run test:dynamic-groups
• npm run test:integration
• npm run test:setup
• npm pack --dry-run
