v0.7.2

Added

• Find/Replace Edit Blocks — the AI can now respond with <<<REPLACE diff blocks that render as a visual find/replace UI in the chat, making targeted code edits easier to review.

Fixed

• Settings Dialog — Provider Dropdown — all providers are now always selectable in the settings dialog regardless of configuration state. Graying out unconfigured providers is kept only in the main toolbar dropdown.
• Settings Dialog — Error Display — API/model errors in the settings dialog are now shown in a fixed-height scrollable area instead of expanding the dialog height indefinitely.
• Settings Dialog — System Prompt — the system prompt field is now scrollable with a fixed height instead of expanding to show all content.

Internal

• Added CI workflow for automated testing and Clippy linting.
• Enhanced AI assistant guidelines for targeted edits and large rewrites.
