fix(v13): persist half_life_chapters through pending_hooks.md roundtrip [phase 7 hotfix 1]

The architect-supplied half_life column was silently dropped by the
projection renderer in both story-markdown.renderHookSnapshot and
state-projections.renderHooksProjection (both emitted only 11 columns).
As a result, hook-stale-detection always fell back to the timing-derived
default (10/30/80), never using the architect-supplied value.

Add a 12th column in the rendered pending_hooks.md table (半衰期 in zh,
half_life in en). Parser already accepted 12 columns; renderer now emits
them. Empty cell still falls back to timing default at detection time.
Backward compat: old 11-column files still parse.
