Paragon: add Builds catalog (saved loadouts with pet park/unpark)

Server-side Character Advancement now stores named, icon-tagged build
recipes (panel-purchased spells + per-spec talent ranks) and atomically
swaps between them by snapshotting the active build, refunding AE/TE
through HandleParagonReset{Talents,Abilities}, and re-spending on the
target recipe. Hunter pets attached to a build are parked to
PET_SAVE_NOT_IN_SLOT (mirroring HandleStableSwapPet) so name, talents,
and exp survive swaps; non-hunter pets (warlock demon, DK ghoul, mage
water elemental) are NOT parked because the engine resummons them from
a fresh template each cast.

New PARAA verbs: Q BUILDS / C BUILD NEW / C BUILD EDIT / C BUILD
DELETE / C BUILD FAVORITE / C BUILD LOAD. The catalog is pushed on
login and after every mutation as a single addon message.

Schema (mod-paragon migration 2026_05_10_03.sql):
- character_paragon_builds (build_id PK, guid, name, icon, is_favorite,
  pet_number, created_at)
- character_paragon_build_spells (build_id, spell_id)
- character_paragon_build_talents (build_id, spec, talent_id, rank)
- character_paragon_active_build (guid PK, build_id)

The talent recipe table is spec-keyed so a build remembers tank/dps
dual-spec layouts independently. Swaps are blocked while in combat.

 |---|---|---|
 | `patch-enUS-4.MPQ` | ~5 MB | DBC + GlueXML bake. Adds `CLASS_PARAGON` (id 12), the character-create slot, glue strings, game-table DBCs, and a patched `Spell.dbc`: **(1)** `RuneCostID` zeroed on every rune-cost spell so non–Death Knight clients still send DK casts (rune costs are shown via `RuneFrame.lua`); **(2)** `Reagent[]` / `ReagentCount[]` zeroed on every spell whose `SpellFamilyName` is non-zero (all class abilities), while profession crafts (`SpellFamilyName == 0`) keep their materials. Both edits mirror server load-time corrections so client preflight and server validation stay aligned. Required for character creation as Paragon to even show up. |
 | `patch-enUS-5.MPQ` | ~57 KB | FrameXML overrides. Replaces stock `PlayerFrame.lua` / `RuneFrame.lua` / `ComboFrame.lua` / `UnitFrame.lua` / `SpellBookFrame.lua` + `SpellBookFrame.xml` with Paragon-aware versions: rune simulator, combo-point simulator, server-authoritative resource sync over the `PARAA` addon channel, action-button usability + click guards, an expanded spellbook (higher `MAX_SPELLS`, 24 skill-line tabs instead of stock 8) so all-class spells render, Paragon stat tooltips on the character sheet (including filtering duplicate “attack power from strength” lines so the paper doll matches server AP), a tooltip post-processor that appends ", Paragon" to the "Classes:" line on class-restricted gear / glyphs (the server bypasses `AllowableClass` for class 12, but the engine paints the line red and omits Paragon — the Lua hook recolors it green and adds the name so the player can tell it's wearable), and **PetFrame** re-anchored so the **pet unit frame sits below the rune row** for Paragon (stock layout had runes overlapping the pet portrait). The paper-doll **ammo slot** follows stock visibility rules (shown for hunters / ranged weapons; hidden when `UnitHasRelicSlot` applies). |
-| `patch-enUS-6.MPQ` | ~123 KB | The `ParagonAdvancement` addon. Replaces the talent pane (`N` key) for Paragon characters with the Character Advancement panel: per-class spell tabs, talent grid, Overview/Search tabs, AE/TE currency, commit / reset / preview, login-time toast suppression, a **PETS** tab with live hunter pet talent trees (preview learn, no TE/AE cost), a dedicated **Reset Pet Talents** control (server `PARAA` `C RESET PET TALENTS` — instant, no gold, no confirmation; requires matching worldserver), and bottom-row **Reset all Abilities / Reset Build / Reset all Talents** disabled while on the PETS tab so those paths cannot dismiss the pet or unlearn Tame Beast. |

Build swaps reset + refund AE/TE, re-spend on the saved recipe, and **park hunter pets** to `PET_SAVE_NOT_IN_SLOT` so their name/talents/exp are preserved across swaps. |
 | `Wow.exe` | ~7.5 MB | 3.3.5a (build 12340) client byte-patched to skip the MPQ signature check so custom `patch-enUS-N.MPQ` files load. Diff against stock is a few bytes; everything else is unchanged. |
 
 Server and client work as a pair: the addon talks to `mod-paragon` on the
 worldserver via `WHISPER` addon-channel messages with the `PARAA` prefix
 (currency push, spell/talent snapshot, commit, combo points, rune
-cooldowns, learn-toast silence window, and **`C RESET PET TALENTS`**
-for hunter pet talent resets from the Character Advancement PETS tab).
