Andrew Hamilton 7e2bb18a85 test: parallel-safe suite (xdist), shared globals session, KICK_DUMP_DIR 
Make ./test.sh -n4 work (~47s vs ~156s serial):

- kick.c: KICK_DUMP_DIR env override for frame-dump .ppm paths
  (default /tmp); per-boot dump_seq counters no longer collide
  across concurrent compositors.
- tests: every spawn gets a unique log file and a per-session dump
  directory owned by the Session (close removes the tree instead of
  globbing /tmp, which raced parallel workers' live dumps).
- 14 protocol-globals tests share one module-scoped keeper session
  via short-lived --globals-out clients instead of 14 boots.
- Two presence-waits converted from fixed sleeps to event waits.
- Harden the fullscreen round-trip: wait for seat keyboard focus
  ([diag] kbd-enter, new debug line in window_enter) before tapping
  F -- map alone does not guarantee enter under load and the tap was
  silently dropped.

Serial remains the deterministic gate (documented in test.sh and
README): a few pre-existing timing-sensitive tests can still flake
under parallel load; they pass alone and serially.

#!/usr/bin/env python3
"""Smoke tests for kick.
The compositor is launched as a nested display (child of the host
Wayland session) and driven over the stdin event feed: raw keyboard
events are packed into binary records and dispatched into the *real*
host key handlers (host_kbd_key / host_kbd_modifiers), so the key
handler logic is under test without needing a focused window or wtype.
Each test launches its own instance (function-scoped fixture), so tests
are independent and can run in any order.
Requires: a live host Wayland session (WAYLAND_DISPLAY) and a prior
./build.sh. Missing prereqs skip the suite.
Known-flaky tests are marked @pytest.mark.flaky; pytest.ini's default
`-m "not flaky"` deselects them from every plain run (including direct
`pytest`). Run them explicitly with `./test.sh -m flaky`.
