laser: feed hold and resume in GRBL mode, the sender-change hold

Stream harness rule 21: a feed hold leaves no dark ground in either mode (lit into the hold, dark while held, lit from the first step out), with realtime and wait-state steps in the session runner. Lifecycle harness: the hold a sender change puts a running job into, the resume that re-arms a held job from the sender and from the button, a reset from a held job, and the resume after the grace closed the window in Hold. Live-fire drills: holdres (the pause as a corner in time, the re-arm after the grace); senderchg follows the hold. BRINGUP: the gapless-pause and sender-change items close, the facts bank gains the measured hold and resume behavior; CAMPAIGN-LOG records the proof and the bench runs. Acceptance: the pause-resume-lid-cancel text follows the behavior; the driver stays covered by src/**.
