Auto-update links after renames, and editing improvements

New

• Update references after renaming. When you rename or move a note, attachment, or folder inside Cogito, a confirmation sheet now offers to update Markdown links, reference definitions, wiki links and embeds, and inline HTML attributes across the rest of the Location.
• Detect bare URLs in Source. A new default-off Editor setting highlights plain http and https URLs in source mode with link tint, underline, Cmd-click, and Open/Copy from the context menu.

Improved

• Smarter indentation inside code blocks. Pressing Return inside fenced Markdown code now carries the current line's leading whitespace forward, and Tab/Shift-Tab also infers the correct indentation unit.

Fixed

• Inline math stays on the line grid. Paragraphs that mix $...$ and prose no longer pick up extra line height, so wrapped lines line up cleanly with the rest of the document.
• Task checkboxes inside tables. Markdown tables that include - [ ] or - [x] task markers now render as preview checkboxes you can click to toggle, instead of showing the raw text. Formatted copy and export include the checkbox inputs too.
