self-review 2026-08-13: seed curiosity from the argmax, not the first word

auto_term_try_slot now passes the WM node's ID to engram_salient_term()
instead of passing its label to a first-word extractor. The runtime scores
every candidate token in the node's text and returns the best one, falling
back from a sentinel label ("memory:remembered") to content — which is the
only reason Memory nodes are visible to the extractor at all. They dominate
working memory, and dynamic seeding had been dead for 50+ consecutive scans
because of it.

Policy stays here: node-type filter, df thresholds, stopword list. The
runtime measures, the soul decides — same split as engram_label_df.

The stopword list stays, and not as belt-and-braces. An earlier draft assumed
the min_df floor would subsume it based on 08-03's finding that function
words have df 0 in labels. Re-measured under word-boundary df: about:2,
whole:1, them:2 — they clear a floor of 1. What keeps them from winning is
the argmax, not the floor.

The old extractor and its five guards are retained as
auto_term_try_slot_legacy, unreferenced, so the reasoning behind each guard
stays readable next to what replaced it. Delete once the new path has a month
of live telemetry.

Live after restart: auto_term producing DRIFT, Wrote; empty streak reset to 0
and holding; activation counts 123-281, within the normal band, no flood.
