196f883c10 fix(player): EnchantmentMask bit fix + Vitae key=0 + absolute Vitals overlay
Three fixes to the Vitals HUD path:

1. EnchantmentMask Vitae/Cooldown bit values (parser regression).
   ACE's enum at references/ACE/Source/ACE.Entity/Enum/EnchantmentCategory.cs
   has Vitae=0x4 and Cooldown=0x8. I had them swapped — when ACE wrote
   the Vitae singleton with mask bit 0x4 set, my parser read it as
   "Cooldown" and tried to consume a count-prefixed list (no count
   present), blowing up with FormatException, returning null from
   TryParse. PlayerDescription consequently failed to parse on every
   live login. Fix: swap the bit values + bucket constants to match ACE.

2. Vitae applies regardless of StatModKey. Live trace showed:
     vitals: PD-ench spell=666 layer=0 bucket=Vitae key=0 val=0.95
   ACE's Vitae enchantment serializes with key=0 (meaning "any vital")
   per retail. EnchantmentMath was filtering Vitae by key like other
   buffs, so the 5% death penalty never applied to Health/Stam/Mana
   max — the Vitals percent read 95% because current=276 / max=290
   (server already reduced current; our max didn't match). Fix:
   Vitae bucket short-circuits the per-key check and applies its
   multiplier to all vitals.

3. Absolute current/max in HUD overlay. VitalsVM exposes
   HealthCurrent/Max, StaminaCurrent/Max, ManaCurrent/Max from
   LocalPlayerState. VitalsPanel overlay format is now
   "current / max (percent%)" when absolutes are available; falls
   back to percent-only pre-PlayerDescription. Matches the retail
   look the user requested ("HP 400/400" style).

Test deltas (841 -> 842):
  - Existing Vitae test still passes (key matches statKey case).
  - New Vitae key=0 test pins the "any vital" semantics.
  - Existing PlayerDescription Vitae singleton test updated to
    write mask=0x4 (was 0x8 with the swapped enum).

Live verification: with +Acdream's Vitae-666 active and Endurance.current=290:
  HP   : current=138, max=145×0.95≈138 → bar 100% (was 95%)
  Stam : current=276, max=290×0.95≈276 → bar 100%
  Mana : current=190, max=200×0.95≈190 → bar 100%
Overlay reads e.g. "276 / 276 (100%)".

bb5003a849 feat(net): #7 PlayerDescriptionParser - enchantment block walker + StatMod flow
Extends PlayerDescriptionParser past the spell block to parse the
Enchantment trailer per holtburger events.rs:462-501 +
magic/types.rs:40. New EnchantmentEntry record carries the full
60-64 byte wire payload:
  u16 spell_id, layer, spell_category, has_spell_set_id
  u32 power_level
  f64 start_time, duration
  u32 caster_guid
  f32 degrade_modifier, degrade_limit
  f64 last_time_degraded
  u32 stat_mod_type, stat_mod_key
  f32 stat_mod_value
  [u32 spell_set_id]?
  + EnchantmentBucket (Multiplicative / Additive / Cooldown / Vitae)

EnchantmentMask outer u32 selects which buckets follow; each bucket
(except Vitae) is u32 count + N records. Vitae is a singleton.

Parsed.Enchantments now exposed as IReadOnlyList<EnchantmentEntry>.
GameEventWiring routes each entry through Spellbook.OnEnchantmentAdded
with the full StatMod data + bucket. EnchantmentMath.GetMod consumes
StatMod records to produce real (Multiplier, Additive) per stat key:

  Bucket 1 (Multiplicative): multiplier *= val
  Bucket 2 (Additive):       additive += val
  Bucket 8 (Vitae):          multiplier *= val (applied last)
  Bucket 4 (Cooldown):       skipped (not a vital mod)

ActiveEnchantmentRecord extended with optional StatModType /
StatModKey / StatModValue / Bucket fields. Existing 4-arg callers
stay compatible (defaults to null / 0). New OnEnchantmentAdded
overload accepts the full record from PlayerDescription path.

Tests: 7 new (834 -> 841):
  - PlayerDescriptionParserTests (2): enchantment block schema with
    multiplicative + additive buckets, Vitae singleton.
  - EnchantmentMathTests (5): multiplicative buffs aggregate, additive
    buffs sum, stat-key mismatch filters out, Vitae applied
    multiplicatively, family-stacking picks higher spell-id.

Closes #7 (parser past spells, enchantment block parsed).
Closes #12 (StatMod flow architecture — data lights up #6's
aggregator). Files #13 (remaining trailer sections: options /
shortcuts / hotbars / desired_comps / spellbook_filters / options2 /
gameplay_options / inventory / equipped — needs the heuristic
gameplay_options walker per holtburger).

Note: ParseMagicUpdateEnchantment (live-update 0x02C2) NOT yet
extended — still uses 4-field summary. PlayerDescription is the
load-bearing path for #6; live updates can be folded in separately.

b153bbe5ad feat(player): #6 fold enchantment buffs into vital max via EnchantmentMath
Ports CEnchantmentRegistry::EnchantAttribute (PDB 0x00594570, see
docs/research/named-retail/acclient_2013_pseudo_c.txt line 416110).
The retail formula:

    real_max = (vital.(ranks+start) + attribute_contribution) * mult_buff + add_buff
    clamp >= 5 if base >= 5 else >= 1

is now applied in LocalPlayerState.GetMaxApprox.

EnchantmentMath.GetMod(activeEnchantments, table, statKey)
  - Family-stacking dedup via SpellTable.Family (only one buff per
    family-bucket wins, by highest spell-id as a generation proxy).
  - Family=0 means "no bucket" — each layer is its own bucket.
  - Returns (Multiplier, Additive) ready to apply.
  - StatKey constants: MaxHealth=1, MaxStamina=3, MaxMana=5
    (verified against named-retail/acclient.h line 37287-37301).

Spellbook.GetVitalMod(statKey) delegates to EnchantmentMath using
its constructor-injected SpellTable.

LocalPlayerState.GetMaxApprox now applies the full formula with
the min-vital floor (matches CreatureVital::GetMaxValue at PDB
0x0058F2DD). When Spellbook is null (back-compat), falls back to
Identity (no buff modification) — existing tests stay green.

GameWindow constructor wires SpellBook -> LocalPlayer so the chain
is complete in the live session.

Architecture in place; data still flat.

Until ISSUES.md #12 lands the wire-format extension that captures
StatMod (type/key/val) on ActiveEnchantmentRecord, the per-enchantment
modifier value isn't aggregated yet — GetMod returns Identity. Once
#12 wires the data, the existing aggregator + formula light up
automatically. Live +Acdream Stam/Mana will keep reading ~95% until
#12 lands.

6 new EnchantmentMathTests cover: empty list returns Identity,
no-table-entries returns Identity, stat-key constants match ACE,
Identity is (1, 0), family-stacking dedup, family=0 (no-bucket).

Total tests: 828 -> 834.

Closes #6 architecturally. Files #12 to track the wire-data follow-up.
