Release v4.4.2

Modaliser v4.4.2

This release includes the existing VSCode development changes alongside
the F1–F20 leader-key support introduced in v4.4.1.

The bundled Companion 1.3.0 adds the VisualJJ focus action and updates editor
activation to target the listed editor group, slot, and label. Editor rows
include every input kind and editor-grid terminals. Activation refuses a
missing or renamed slot; stale-file cleanup still requires the original tab.

(modaliser apps vscode) exports focus-visualjj, so configurations using
that action load successfully. The shipped VSCode example includes a
VisualJJ binding. Existing F17/F18 leaders remain supported, and F2/F1 can
be added as global/local leaders in the same leaders setting.

Adoption

Upgrade Modaliser and relaunch it. If Companion 1.3.0 is not already
installed, use Install VSCode Companion, then restart VSCode.
Your configuration is preserved during an upgrade.
