Battle Master:
- New "superiority" resource pool (4/long-rest at L5), provisioned via
initSubclassResources at !subclass selection.
- Three armed maneuvers fueled by superiority dice:
* Precision Attack — +d8 (≈+4) to first attack roll
* Tripping Attack — enemy skips first attack (reuses Phase 9
SpellEnemySkipFirst)
* Rally — +(d8 + CHA) HealItem at <50% HP
- L7 Know Your Enemy proxied as +1 AttackBonus passive.
Assassin:
- L5 Assassinate: AssassinateAdvantage (re-roll first miss, take better
of two d20s) + AssassinateBonusDmg = level (5 at L5) stacked on top
of the Rogue's existing Sneak Attack auto-crit.
- L7 Impostor bumps the bonus damage by +3.
- L5 Infiltration Expertise → +5 Deception; L7 Impostor → +10.
Engine:
- CombatModifiers gains FirstAttackBonus, AssassinateAdvantage,
AssassinateBonusDmg.
- resolvePlayerAttack consumes each on the first attack only via new
combatState one-shot flags.
Tests added: 14 covering passive gating (BM L7+, Assassin L5/L7),
maneuver Apply flags, superiority pool init for BM only, !arm gating
across class/subclass for precision_attack, Deception bonus tiers,
statistical lift from FirstAttackBonus and AssassinateBonusDmg in
SimulateCombat.

Implements the identity layer of gogobee_subclass_system.md: 15 subclasses
(3 per class) selectable at L5 via !subclass.
- Schema: new subclass + last_subclass_respec_at columns on dnd_character.
- Registry (dnd_subclass.go): 15 entries with class, display, tagline, and
TwinBee flavor line; helpers for prompt rendering and input resolution
(number, id, or display-name; case/space/hyphen-insensitive).
- !subclass command: bare form prints prompt or current; !subclass <name>
selects (free first time) or changes (500 euros + 30-day cooldown via
separate timestamp from the full !respec wipe). Save-then-debit ordering
mirrors !respec audit fix B.
- Level-up DM at L5+ now embeds the real selection prompt instead of the
Phase 9 placeholder; suppressed once a subclass is set.
- Sheet shows the subclass below the class line, or nudges !subclass when
unchosen at L5+.
- Existing !respec full-wipe also clears subclass + cooldown timestamp.
Mechanical effects of L5/7/10/15 subclass abilities deferred to SUB2/SUB3.
