Extract inline @code blocks from vt headers (size_report.h, modes.h,
sgr.h, paste.h, mouse.h, key.h) into standalone buildable examples
under example/. Each header now uses Doxygen @snippet tags to include
code from the example source files, keeping documentation in sync
with code that is verified to compile and run.
New example projects: c-vt-size-report and c-vt-modes. Existing
examples (c-vt-sgr, c-vt-paste, c-vt-mouse-encode, c-vt-key-encode)
gain snippet markers so their code can be referenced from the headers.
Conceptual snippets in key.h, mouse.h, and key/encoder.h that show
terminal-state usage patterns remain inline since they cannot be
compiled standalone.
Add ghostty_size_report_encode() to libghostty-vt, following the
same pattern as focus encoding: a single stateless function that
writes a terminal size report escape sequence into a caller-provided
buffer.
The size_report.zig Style enum and Size struct now use lib.Enum and
lib.Struct so the types are automatically C-compatible when building
with c_abi, eliminating the need for duplicate type definitions in
the C wrapper. The C wrapper in c/size_report.zig re-exports these
types directly and provides the callconv(.c) encode entry point.
Supports mode 2048 in-band reports and XTWINOPS responses (CSI 14 t,
CSI 16 t, CSI 18 t).
