A bad pathspec in a multi-file `git add` made the whole invocation a no-op except for
the 4 deletions already staged from an earlier `git rm` - Network.mqh's new inline
declarations, AI_NETWORK.md's table update, and the 4 new AI/Impl/*.mqh bodies never
landed in 46523dc. Same content already compiled clean; this just gets it into the
index. Tree is correct as of this commit; 46523dc alone is not.
