…→ MeosType Updates the MEOS vcpkg port to MobilityDB/MobilityDB@2c4243a265 which exposes MeosType (CamelCase). Removes the broken forward-compat alias `using meosType = MeosType` from tydef.hpp and renames all uses site-wide. Platform-compat fixes included: - macOS arm64: bigint_to_set_i64 trampoline bridges int64 (long) vs int64_t (long long) mismatch in SetUnionAgg registration. - wasm32-emscripten: portfile patches pg_bitutils.h so that __builtin_clz/ctzll is selected when SIZEOF_LONG_LONG is not set by configure. Per-thread MEOS initialisation (EnsureMeosThreadInitialized) added via meos_thread.hpp so that DuckDB worker threads do not crash with NULL session_timezone when unnest/parallel pipelines dispatch onto them.
MEOS now inserts a turning point in round(f(linear_seq)) for transcendental functions (ln, log10, exp) where f is concave/convex, per PR MobilityDB/MobilityDB#1003.

The vcpkg portfile fetches estebanzimanyi/MobilityDB at 278863520b (tag ecosystem-pin-2026-06-06g, SHA512 2e617cac4bfed919eee8bd73e35f9b3da8ffd7a51f68104a9497c0d3339dbb1af4a2ec6feab3e8fffb880481badf86c352ad1efb39cab533de19d2c1192a8e5b). The MEOS 1.4 API exposes MeosType (CamelCase); every call-site in MobilityDuck uses MeosType directly and the forward-compat alias in tydef.hpp is removed.
