inject harness layer framing across all docs and source files

CrazyBoyM · CrazyBoyM · commit 8aca857a753e · 2026-03-17T22:24:09.000+08:00
Every session doc (s01-s12, 3 languages = 36 files) now opens with a
one-line harness layer callout after the motto. Every Python agent file
(13 files) now opens with a harness comment before the docstring.
Consistent terminology: the loop belongs to the agent, the mechanism
belongs to the harness.
