Release 0.12.9-alpha

Release 0.12.9-alpha: copy/AtlasLoot, LFM composer rework, PvP detection, UI cleanup
Covers 0.12.3-alpha through 0.12.9-alpha.

Inspector:
Right-click a player row to copy the name; right-click a gear row to open
the item in AtlasLoot (Shift+right-click copies the item value).
PvP gear detection via resilience (GetItemStats key match + tooltip fallback):
PvP items shown orange with a PVP tag, audit shows pvp=N, player name orange.
Share summary now reports "PvP Items: N".
Removed the Advanced/Easy dropdown (always easy), the Filter/Status buttons,
the Save One button, and the live queue/ready counts line.
Renamed Report -> Save All; added a Guild share channel.
Player names no longer show the -Realm suffix.
Added a "? Info" help dialog; enlarged the window and tightened spacing.

LFM:
Replaced the class/spec checkbox grid with a Tank/Healer/Melee/Ranged Need
table (count + free-text classes) and per-field clear buttons.
Custom numeric Delay and Repeat inputs, plus Cancel to stop pending posts.
Added a /guild channel checkbox.
Achievements can be linked into the focused LFM box directly from the
Achievement window (hooks HandleModifiedItemClick and the tracking toggle).

Slash:
/ri opens the window; /ri help lists commands; added /ri cancel.
