Track floating-terminal v0.5.0

[vburojevic]

Bumps floating-terminal from ^0.4.0 to ^0.5.0 — a caret range on 0.x is
minor-locked, so the listing cannot see v0.5.0 without this.

What v0.5.0 adds

A polish pass over the whole plugin:

• Find in scrollback — Cmd/Ctrl+F inside the terminal (or a find key on
  the mobile bar): highlighted matches, counts, Enter/Shift+Enter navigation.
• Jump to latest — a pill appears when the view is parked in history, and
  never in the alternate screen.
• Maximize/restore on desktop (button + titlebar double-click), and
  middle-click closes a tab.
• Touch targets: on a coarse pointer the tab strip grows to 48px with an
  always-visible close control.
• xterm's scrollbar slider now themed from bb's tokens; fling honours
  prefers-reduced-motion; ^R added to the mobile key bar.

Checks

• 77 unit tests, typecheck, bb plugin build
• Fresh git clone --branch v0.5.0 + npm install --omit=dev + build
• 5-configuration mobile matrix (Galaxy S9+, iPhone 14 Pro, Pixel 7, iPhone
  under WebKit, iPad Pro 11) — twice, plus desktop geometry regression scripts
• All features runtime-verified against a live pty

No new permissions, services, or network access. One new bundled dependency:
@xterm/addon-search (MIT, same xterm.js project as the terminal itself).
