RC-Diablo Orbs

Here's everything that changed and why:

TOC files (new) — The game loads the most specific TOC it recognizes. Same Lua files in all of them, zero code duplication:

• RCDiabloOrbs_TBC.toc — Interface 20504 (TBC Anniversary)
• RCDiabloOrbs_Wrath.toc — Interface 30403
• RCDiabloOrbs_Cata.toc — Interface 40400
• RCDiabloOrbs.toc — Interface 50401 (MoP Classic, unchanged)
• RCDiabloOrbs_Mainline.toc — Interface 110107 (retail)

Left-click fix for TBC — The health/mana orbs were at SetFrameStrata("LOW"). The default Blizzard PlayerFrame in TBC sits at MEDIUM in the exact same bottom-left corner, eating all the clicks before they reach the orb. On TBC/Wrath the orbs now use MEDIUM strata. MoP is unchanged at LOW since most MoP users hide the default frame anyway.

Right-click fix for TBC/Wrath/Cata — SetAttribute("type2", "togglemenu") on a SecureActionButton is unreliable pre-MoP. Both the player orb and pet orb now use a plain OnMouseUp script for those versions instead, falling back to togglemenu on MoP where it works.

C_Timer.After polyfill — This API doesn't exist in TBC/Wrath/Cata. Added a simple OnUpdate-based polyfill so the welcome popup on first login still works.

GetComboPoints for MoP — Removed in MoP, replaced by UnitPower("player", 4). Both combo point tracking calls now branch on RC32_IS_MOP_OR_LATER.

RegisterUnitWatch guard — Only exists Wrath+. Wrapped with a nil check, and added PLAYER_LOGIN/PLAYER_ENTERING_WORLD event handling to manually show/hide the pet orb on TBC.

CreateGlow pcall — The PlayerModel + .m2 path combination can throw errors on versions where the model path is missing. Wrapped in pcall so it fails silently instead of breaking the addon.
