+- Tighten terminal command blocking during tool execution
+- Sanitize version scopes before running npm install
+- Terminal: improve blocking rules and related command handling
+- Terminal: keep stdout processing stable while filtering sentinel output
+- Install flow: sanitize npm version scopes before invoking installs
+- Marketplace: keep prerelease package handling aligned with tool registry metadata
+- Tools: preserve capability metadata for npm and locally loaded tools
+- Tool registry and preload APIs now carry prerelease package support end to end
+- Terminal manager refactor expands the blocking pipeline and stdout handling internals
