Add a full-featured terminal Emacs 30.2

Message

Replaces nothing: recipes/emacs-nox.sgl stays as it is. This is the same version built with the opposite intent. sqlite3, tree-sitter, zlib, dynamic modules and elisp threads are on, and JSON needs no dependency because Emacs 30 has it in-tree.

Verified by running the binary, not by reading configure output. emacs -nw starts in a real pty (TUI-FRAME=t COLS=80 LINES=23 DISPLAY=nil), and sqlite, JSON and zlib each do actual work rather than answering an availability predicate: a two-row table is created and selected back, a plist round-trips through json-serialize and json-parse-string, and 81 gzip bytes inflate to their original text. treesit-library-abi-version reports 14, matching the ABI measured directly against the built libtree-sitter.

libxml2 is switched OFF EXPLICITLY, and that is the finding rather than a preference. The seed's pkgconf 1.9.5 aborts on any .pc file with an empty dependency-list field, and libxml2 installs Requires: empty. Emacs looks for libxml2 through PKGCHECKMODULES, reads SIGABRT as "not present", and configure still exits 0 -- so the default would have produced an Emacs silently missing a requested feature. Saying --without-xml2 makes the definition state a fact.

The cause was isolated by running Emacs' own configure twice in a replica of the build environment, changing one variable: with LIBXML2CFLAGS and LIBXML2LIBS set, PKGCHECKMODULES skips pkg-config and detection succeeds. That fix cannot be written into the package, because those values need libxml2's store prefix and a phase argument has no way to name a dependency's path.

Native compilation is absent by decision, recorded in the module header.
