Incoprea curated font library — 54 distinct families

Le Murmure, Basteleur and Pilowlava join the 49-family curated baseline.
New original Incoprea designs: Incoprea Lantern Stencil, Incoprea Tideglass.
Named styles are not counted as additional families. All desktop and webfont binaries are unchanged.
Every family includes its original license and source attribution.
Foldline build-source paths and their checksum records were made portable; its font binaries and proofs are unchanged.
The previous release readme is preserved unchanged in history/README-v2.txt.
The earlier 250-entry experimental collection remains a separate archive.
