fourteen settings go live, /leave holds, and /assist can swing

- mouse-look speed is cameraYawMoveSpeed and cameraPitchMoveSpeed, so pfUI's afkcam does what it asks and an addon driving the stock Interface Options window runs its load and Defaults walks to the end; the shipped feel does not move (2147)
- the eight combat-log range sliders are real settings, so BigWigs' Range plugin and DPSMate read and write them, and the Show Pet Melee Damage and periodic-spell settings genuinely silence what they gate (2147)
- the stock Sound Options window loads hidden beside ours for addons to find, and its three check-box settings are real: the listener sits at your character, emote voices can be muted, zone music can loop without its silence gap (2147)
- /assist with assistAttack set selects and starts swinging; /leave General survives a relog, a /join puts the channel back in its chat window's list, and SetGuildRecruitmentMode joins and leaves GuildRecruitment - City (2144)
- wipe, strsplit, strjoin, strtrim, strconcat and tostringall are gone: no 1.12 client has them, and the addons that call them are multi-client builds whose vanilla path raises on the real client too (2146)
