…grid Coalesce terminal rendering to a single flush per visible pane per step while expanding synchronous terminal emulation work so benchmark timing is not dominated by off-thread canvas redraws. Bundle the vendor-neutral DejaVu Sans Mono font locally and normalize terminal cell dimensions across engines and device pixel ratios for deterministic cross-browser execution.
Ensure each benchmark step takes at least 20 ms on desktop by exercising representative terminal emulator subsystems instead of synthetic loops. This balances all four steps around 25-29 ms on desktop while keeping cross-browser execution deterministic and low-noise.
…step Move multi-pane terminal instantiation, addon setup, initial shell session parsing, and glyph atlas warmup out of the unmeasured prepare phase into a dedicated InitTerminals step. The prepare phase now only waits for bundled local fonts to resolve so startup overhead is measured fairly across browsers without network dependencies.
Integrate latest upstream changes and emit resources.txt during the terminal-xterm bundle build for suite manifest validation.

Apply repository Prettier and ESLint formatting rules to terminal-xterm sources and README so the CI formatter check passes cleanly.
…imer state Dispose RenderService's IntersectionObserver on hidden panes and clear redundant viewport initialization timers so InitTerminals maintains identical pause state and sync/async boundaries across Chromium, Firefox, and WebKit.

Uses the shared generateResourcesFile helper and registers the file in suites.mjs. In WebKit#567 this came in with the merge of upstream main (2b68b69).
