Agent Tool 0.1.2

Changed

• Dashboard rows now show an "Updates available" marker, so it is clear which tools the update count refers to.
• Clicking the "Updates available" count filters the list down to the tools that have an update; clicking it again clears the filter.
• The Dashboard shows a loading indicator until the first scan finishes, instead of looking like an empty or failed list.
• The tool list is posted before the agent CLI scan, so the first view no longer waits on spawning login shells.
• MCP status checks no longer start a new round while the previous one is still running.
• Packaging now starts from a clean build directory.

Fixed

• Update previews, configuration files, registry reads, and GitHub API responses are now bounded, so a single large input cannot grow the extension host's memory without limit.
