What's New in v0.2.1

Prominently Highlighted [a] Add Server:
- Restored and highlighted [a] Add Server in bold cyan across all footers:
  - Servers List: [a] Add Server · [Enter] Inspect · [Space] Toggle · [t] Playground · [/] Filter · [d] Remove · [?] Help
  - Server Details Inspector: [h/Esc] Back · [1-5] Tabs · [a] Add Server · [c] Copy · [t] Playground · [j/k] Scroll
  - Clients & Harnesses Matrix: [Tab/1] Servers · [a] Add Server · [j/k] Navigate · [u] Sync · [d] Remove · [r] Rescan · [?] Help · [q] Quit
Overview Quick Actions: The Overview sub-tab of the Server Inspector now highlights [a] Add Server at the front of the quick action shortcuts.
Global Keystroke Support: Pressing a now reliably launches the Add Server Wizard from any screen (Server List, Server Inspector, or Clients & Harnesses View).
Zero-State / Empty Search Guidance: When 0 servers are configured (or 0 match the search filter), the list pane displays an instructional banner prompting the operator to press [a] to add from the catalog or [u] to auto-sync.
Dynamic SemVer Display: Header and footer dynamically resolve and render env!("CARGO_PKG_VERSION") with clean column alignment.
