M6.9: Cervidae + Ursidae clade rebuild

Restore the canonical clade content from theriapolis-rpg-clades.md.

Cervidae traits: Prey Sense (cannot be surprised, +WIS to initiative
twice, advantage on hidden-creature Perception), Flight Response
(reaction half-speed move on hostile-adjacent, prof-bonus uses),
Pivoting Ears (advantage hearing-Perception, cannot be flanked) —
replacing the misplaced Antlers and Fleet-Footed and the reduced
Wide Field of View. Detriments: Freeze Response (stun on first
undetected damage), Predator Aversion (CHA disadvantage near
aggressive predator clades) — replacing the misplaced clade-level
Flight Response (now correctly a trait) and Delicate Frame.

Ursidae traits: Massive Frame (size category Large outright, advantage
STR, doubled carry, Heavy weapons, one-paw -2-size grapple) —
upgrading from the reduced Powerful Build; Thick Hide (AC 12 + CON,
not the wrong 11 + DEX, dropping the un-doc'd bludgeoning resistance);
Hibernation Recovery (full hit-dice on long rest, 24-hour sleep
clears one exhaustion/disease/poison) — replacing the misplaced
Bone-Crushing Jaws (which belongs at species level on a per-bear
basis). Detriments: Ponderous (speed 25, disadvantage DEX area saves,
init -2) — restoring the speed and initiative penalties dropped by
Lumbering; Infrastructure Problem (CHA disadvantage in non-Large
spaces) — replacing the misplaced Heat Intolerance.

Migrate Delicate Frame down to Deer-Folk as Slight Frame (where the
doc puts it), since the clade-level slot is now Predator Aversion.
Heat Intolerance / Bone-Crushing Jaws drop entirely from Ursidae —
they belong on per-species records (Polar Bear's Heat Vulnerable,
Brown Bear's Devastating Swipe), which are part of audit item #5.
