OSC 8 hyperlinks landed in #3248, but detectCapabilities() returned
hyperlinks: true in the unknown-terminal fallback. Terminals that
silently swallow OSC 8 (most xterm-compatible hosts, tmux/screen
without passthrough) end up dropping the URL from rendered markdown
links entirely, since the fallback 'text (url)' rendering is skipped
whenever hyperlinks is true.
- Unknown terminals now default to hyperlinks: false.
- tmux and screen (TMUX env, TERM starting with tmux/screen) force
hyperlinks: false even when the outer terminal would otherwise
advertise OSC 8 support. Image protocols also left disabled.
- Added detectCapabilities tests covering the known-capable set and
the tmux/screen/unknown cases.

The Zellij-specific Kitty-query skip regresses Shift+Enter newline handling in Zellij. Restoring the previous behavior for now while we work on a safer fix that preserves both Alt and modified Enter handling.\n\nContext: https://github.com/badlogic/pi-mono/issues/3259
Tests assumed renders complete synchronously after requestRender() +
nextTick + flush(), but commit 6f5f37f8 changed requestRender() to
schedule via setTimeout with a 16ms minimum interval. Tests reading
viewport state before doRender() runs saw stale data.
Add VirtualTerminal.waitForRender() helper that waits for the throttled
render to settle (nextTick + 20ms + xterm flush), and replace all
terminal.flush() calls after render-triggering actions with it.
Fixes 8 failing tests across overlay-short-content, tui-render, and
markdown test suites.
