Replace the M2 stub rasterizer with a real font rasterizer:
- build.zig.zon: add TrueType as a lazy path dependency
- build.zig: swap stub_rasterizer_mod for truetype_rasterizer_mod; link
fontconfig + libc on Linux; TrueType dep is lazy (falls back gracefully)
- src/gui/rasterizer/truetype.zig: andrewrk/TrueType rasterizer; loadFont
uses fontconfig to locate the font file, derives cell dimensions from
vertical metrics (ascent−descent) and 'M' advance width; render blits the
A8 glyph bitmap into the caller-provided staging buffer with correct
baseline placement (ascent_px + off_y) and double-wide support (+cell_w
x-offset for kind=.right); arena allocator per render call
- src/gui/rasterizer/font_finder.zig: OS dispatcher (Linux only for now)
- src/gui/rasterizer/font_finder/linux.zig: fontconfig C API - FcFontMatch
resolves a font name pattern to an absolute file path
Requires: libfontconfig-dev (already present alongside libgl-dev etc.)

Move shared types out of src/win32/ into a new src/gui/ package:
- xy.zig: generic XY(T) coordinate type
- xterm.zig: 256-color palette table (used by all GPU renderers)
- GlyphIndexCache.zig: glyph→atlas-slot mapping
- Cell.zig: Rgba8 and Cell extracted from d3d11.zig
- GlyphRasterizer.zig: comptime interface spec/checker
Update src/win32/ imports to point to ../gui/ and delete the
moved originals.
Replace the -Dgui bool option with -Drenderer enum { terminal, gui,
d3d11 }, wiring .d3d11 to the existing win32 DirectWrite path and
keeping build_options.gui = (renderer != .terminal) for tui.zig.

This is a major update of the tree-sitter depedencies (via flow-syntax). In
addtion to updating tree-sitter from the 0.24 branch to 0.26 there are also
updates to all tree-sitter parsers and a couple of new languages. The
supported tree-sitter ABI is now at version 15. (min version still 13)
New languages:
d (dlang)
llvm (LLVM IR)
comment (tags in comment blocks in many languages)
query (tree-sitter queries)
rpmbash (bash embedded in rpmspec files)
This should also unblock a few other file type requests, but they are not
included here directly and will follow later.

Now that Widget addresses do not have to be stable we can greatly simplfy
and in the process eliminate the potential for update looping.
