dev: Limit devcontainer memory usage to 8GB (#1604)

Devconatiner memory usage is currently unbounded. This allows runaway processes (like rust-analyzer) to monopolize system resources, causing memory exhaustion for the host OS. This change adds a limit so that the oomkiller reaps devcontainer processes when they exceed 8GB. Signed-off-by: Oliver Gould <[email protected]>
