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.

Also, move blame parser and related structures to a new module VcsBlame.
This includes a full parser re-write to take advantage of the slightly
more efficient incremental output format.
Now just plain `--release` will build the release just for the native cpu arch and os.
Adding `-Dall_targets` will build all targets in the known good list.

The native backends for zig are still very slow. Enable llvm by default so debug
builds are generally useable. For quick builds, explicitly disable llvm with
`-Duse_llvm=false`.
