* fix(smartplaylists): merge negated artist/tag rules in AND groups Smart playlists with many negated role/tag conditions ANDed together (e.g. 100+ "isNot artist" rules, issue #5511) generated one correlated NOT EXISTS subquery per rule, scanning media_file_artists for every candidate row. On large libraries this took minutes and triggered API timeouts and SQLite lock contention. By De Morgan, "NOT EXISTS(role=X) AND NOT EXISTS(role=Y)" is equivalent to "NOT EXISTS(role=X OR role=Y)", so multiple negated conditions for the same field can be collapsed into a single batched NOT EXISTS. This mirrors the existing OR-group merge that #5515 added for positive conditions. The shared grouping/batching logic is extracted into mergeSameFieldConds, parameterized by polarity, so the OR/positive and AND/negated paths reuse one algorithm instead of duplicating it. roleCondGroup/tagCondGroup gain a 'not' flag to emit the negated subquery. Benchmark (323k tracks, 120 isNot artist rules, reporter's exact shape): merged ~54ms vs unmerged ~8.7s steady-state (~160x faster). * docs: trim redundant comments on merge helpers The De Morgan explanation was repeated across three doc comments. Keep it in one place (mergeNegatedJsonConds, where negation is introduced) and reduce the shared core and group-type comments to concise one-liners.
