Previously every file in the terminal package independently imported build_options and ../lib/main.zig, then computed the same lib_target constant. This was repetitive and meant each file needed both imports just to get the target. Introduce src/terminal/lib.zig which computes the target once and re-exports the commonly used lib types (Enum, TaggedUnion, Struct, String, checkGhosttyHEnum, structSizedFieldFits). All terminal package files now import lib.zig and use lib.target instead of the local lib_target constant, removing the per-file boilerplate.
