chore(newos4): commit accumulated maintenance outputHEADv4.6.156main

The daily collector and the feedback pipeline had left 57 modified files uncommitted (skills,
modules-index, CHANGELOG, feedback decisions, debug counters). The public mirror publishes git
HEAD, so without this the published repo stayed behind the tree - and it blocked the publisher
outright once uncommitted subtrees started failing loudly.
