Fix egal_wie_pun answer key: Bruyne, not Braeune (verified against the real circulating joke; the documented punchline names the footballer directly, the tan-word is the phonetic gloss, not the written answer)

Fix middle_letters item: REH -> ZEH (answer REH was leaking into the input word list; ZEH also completes the Arm/Zeh/Ohr body-part pattern)

Fix distractor in schwarz-weiss riddle: Schachbrett -> Panda (Schachbrett was an equally valid answer under the stated criteria)

round-2 language+correctness review (1861 items)

Fluency pass: 299 adjudicated grammar/agreement fixes (incl. systematic template bugs: power_strip dative, word_half plural agreement, weekday_offset/transitive phrasing). README untouched.

Fix three_tier_liar: answer option no longer mixes an always-liar with the truth-teller (logical contradiction). 1 item corrected; generator constraint fixed at source.

Fix hard subset: generated hard = robust set (missed by high+xhigh+low), 119->109

Merge grips-extended: 925 -> 1861 generated reference items
