M6.11: Mustelidae line restoration

Clade: rename + restore traits to doc-canonical Metabolic Furnace
(cold advantage), Sinuous Body (squeeze + escape), Ferocity (+2 to
melee at half HP, not the JSON's reduced one-shot +1). Detriments:
rename High Metabolism → Burn Rate (doc name) and replace the
JSON-only Scent Marker with Short Fuse (disadvantage on WIS saves
vs. effects provoking rage/aggression — the missing half of the
clade detriment pair).

Ferret-Folk: replace Weaver / Social Charm / Small Frame with
War Dance (bonus-action evasion bonus, prof-bonus uses), Tunnel
Runner (15 ft. burrow + tunnel mastery), Irrepressible (advantage
vs. frightened). Detriments: Attention Deficit (sustained-focus
disadvantage outside combat), Musk Broadcast (stress amplifies
scent involuntarily).

Badger-Folk: replace Burrower / Tenacious Grip / Stocky Build with
Immovable (advantage STR/CON vs. move/prone), Digging Claws (20 ft.
burrow + 1d6 + STR claws + barrier-break advantage; was 10 ft. with
no claw damage), Relentless Endurance (CON-save reaction to drop to
1 HP from 0). Detriments: Tunnel Vision (lock-on Perception
disadvantage), Antisocial Default (CHA disadvantage in groups of
6+). Bumped base_speed to 30; the JSON-only Stocky Build's speed-25
was not in the doc.

Wolverine-Folk: replace Savage Jaws / Indomitable Ferocity / Feared
Kin with Wolverine's Frenzy (renamed from doc's "Feral Rage" to
avoid collision with the Feral class — same mechanic: 1/long rest
1-minute resistance to all damage except psychic), Jaws of Iron
(1d8 + STR bite that chews through soft materials as actions),
Arctic Survivor (cold-environment immunity, no tracks in snow,
arctic Survival advantage). Detriments: Berserker's Toll (one
exhaustion after Frenzy), Feared, Not Loved (CHA persuasion
disadvantage with creatures who know what you are).
