ci: drive gate exercises mouse/keyboard/iframe/canvas, not just navigate+eval

An adversarial audit of the pipeline found the drive gate only did goto+evaluate,
so several historically-shipped breakages would still pass it green:
- firefox-2 (jugglerSendMouseEvent missing) — no mouse/keyboard was tested
- issue #20 (cross-origin iframe content_frame() None) — no iframe was tested
- canvas non-determinism (stealth seed) and headless navigator tells

ci_drive_gate.py now clicks a button, moves the mouse, types into an input,
reaches into an iframe, checks an identical canvas draw is byte-stable, and
checks navigator.languages/plugins — all offline (data: URLs), GPU-free, no
proxy. Validated against the real build.

Pipeline hardening from the same audit:
- Windows: stop swallowing `mach package` failure and never fall back to the
  dev tree dist/bin (that masked the firefox-7/8 packaging bugs)
- macOS: plutil -lint Info.plist + required-key checks (a malformed plist ships
  fine through a headless drive but Finder calls the .app "damaged")
- publish: assert all 5 archives present + fail_on_unmatched_files (no silent
  partial release if a build leg drops out)

"""CI drive gate — the firefox-8 catcher.
"""CI drive gate — the firefox-N catcher.
A raw `firefox --screenshot` proves nothing about automation: a juggler-less
binary renders a screenshot just fine and ships broken (firefox-8 did exactly
that). This DRIVES the binary the way users will Playwright launches it over
the juggler pipe, loads a real page, and round-trips JS. A binary with a
missing/broken juggler throws TargetClosedError here and the gate fails.
the juggler pipe and exercises the input/DOM paths real callers depend on.
Headless, NO screenshot GPU-free, so it can't false-fail on GPU-less hosted
runners. Zero proxy / zero secrets safe in public CI. (The proxy realness
gate fppro/webrtc stays local, it needs secrets.)
It deliberately covers the failure modes that HISTORICALLY shipped green:
- juggler missing entirely TargetClosedError on launch (firefox-8)
- mouse/keyboard input broken click/move/type assertions (firefox-2 #9:
jugglerSendMouseEvent / synthesizeMouseEvent)
- cross-origin iframe broken content_frame() reachable (issue #20)
- canvas non-deterministic identical draw identical dataURL (stealth
seed must be per-session, not per-readback)
- headless navigator tells navigator.webdriver falsy, languages
non-empty, plugins is a real PluginArray
All of this is headless, NO screenshot GPU-free (can't false-fail on the
GPU-less hosted runners), and fully offline data: URLs only, NO network, NO
proxy, NO secrets safe in public CI. WebGL determinism is intentionally NOT
checked here (it needs SWGL and can false-fail headless); it lives in the local
proxy realness gate, alongside the fingerprint/WebRTC-vs-vanilla checks.
Usage: python ci_drive_gate.py /path/to/firefox[.exe | .app/Contents/MacOS/firefox]
Exit 0 + "DRIVE GATE OK ..." on success; non-zero with a reason on failure.
