Summary
Adds neg(p) negation pattern combinator, lowers variant inline dispatch threshold from 16 to 8, and adds a compile-fail diagnostic for val<> runtime value misuse.
Changes
include/ptn/pattern/negation.hppinclude/ptn/patternia.hppinclude/ptn/core/common/optimize.hppk_variant_inline_dispatch_alt_threshold16 → 8tests/tests_combinator.cpptests/CMakeLists.txttests/compile_fail/val_requires_compile_time_constant.cppTests
Risk
Low. neg(p) is a new combinator with zero binding — does not affect existing match paths. Threshold change 16→8 only affects variant dispatch strategy (hot inline path for ≤8 alternatives), existing paths unchanged.
