Rename the capnp/ module set to zap/ and the capnpc compiler to zapc; rename all .capnp schemas and fixtures to .zap; update every import, include guard (isInZap), generated-code emission, exception type (ZapFormatError), and the macro-generated zapUnpackStructImpl/ zapPackStructImpl identifiers to the ZAP brand. Zero capnp/Cap'n Proto references remain in source or build files; upstream MIT attribution (Sandstorm, Michał Zieliński) is preserved. Raise the nimble nim floor from the fictional 0.12.0 to the locked, verified 0.15.2 (matches nimenv.cfg/build.sh; code carries fixes through Nim 0.18). Rewrite TODO.md as honest, source-anchored known-limitations (two-word intersegment pointers, nested/named-union codegen, RPC interface inheritance) instead of a bare wishlist.
