Editor fixes for selections, copy and paste, the global shortcut removed, and the version bump to 0.8.0.

Editor

• Text style keys, Tab, indent and move line act on every selected line and keep the selection. Before, a triple-click or Shift+Down styled the next line, and a multi-line selection or Ctrl+A styled one line.
• A heading and body selected together no longer become a list nested inside the heading.
• Typing, Backspace, paste or cut on a triple-clicked line no longer pulls up the line after it.
• Chrome's inline style spans (line merges, list changes, Ctrl+B in a heading) are removed after each edit.
• Enter on a selection reaching the end of a heading replaces the selection.

Copy and paste

• Copy leaves out the stray empty line or bullet and any inline styles.
• Paste is cleaned before it enters the note: line breaks of a page's HTML source no longer show, each plain text line is its own line (including CRLF), Google Docs copies are no longer all bold, and Docs or Word list items no longer hold a paragraph. Lines pasted into a list become items.

Behaviour changes

• Ctrl+Alt+N is gone; the tray icon brings the window back.
• A link opens with Ctrl+click (a plain click in a read-only note still opens it), so a plain or double click can place the caret and select its text.
• Punctuation after a typed URL stays out of the link.

Testing

• npm test: 208 pass.
• 85 cases with trusted keyboard and mouse input against the real notes.html in headless Chrome on Linux: all pass. That script is not in this repo.
• Not run locally: the Rust build and the end-to-end tests, which this PR's CI covers. Nothing here has been tried by hand in WebView2.

Known limits

• HTML paragraphs pasted into the middle of a list item join with a line break instead of becoming items.
• Bold or italic set only through CSS on pasted text is dropped.
• Undo restores the caret, not the selection.
