frostebiteandClaude Opus 5 adaf7cd8f4 fix(docker): pass --shm-size so Unity 6.6+ builds work (backport)
Unity 6.6+ editors request 1GiB of shared memory and hard-fail with
"Insufficient shared memory available - if using Docker, please run the
container with --shm-size=1025M" against Docker's 64m default.

This action never passed --shm-size at all and exposed no input to work
around it, so affected users had no escape hatch whatsoever. Reported as
#840 (closed as not-planned) and again on Discord against Unity
6000.6.0f1.

Backport of the fix already merged into game-ci/cli (#239), which owns
this code going forward. Adds the dockerShmSize input, the
BuildParameters field, and the flag on both the Linux and Windows
commands, defaulting to 1025m - the value unity-test-runner has always
passed. --shm-size caps a tmpfs rather than preallocating memory, so the
default costs nothing for editors that don't need it. "0"/"none" opts
back out to Docker's own default.
