feat: 8x8 block granularity, double-res text glyphs, and PlaneGrid

Add 8x8 block resolution for the encoder. Each grid character maps to
an 8x8 block (4 per macroblock) with proper AC residual encoding at
quadrant boundaries using a forward 4x4 integer DCT.

Introduce PlaneGrid type for direct Y/Cb/Cr value planes with no
character-count limit, supporting both 16x16 and 8x8 block granularity.
All CLI output paths now use PlaneGrid as intermediate representation.

Add 6x10 double-resolution font (Glyph2x) for 8x8 block mode, giving
4x the glyph detail of the 3x5 font at the same pixel footprint.
Even text scales (2, 4, 6...) in 16x16 mode auto-select the 2x font
for sharper glyphs without requiring -8x8.

Text character set aligned across both fonts: A-Z 0-9 and
! # % + - . / : = ? [ ] _ ( ) plus space. Lowercase a-z and
rarely-used punctuation removed; lowercase input auto-uppercased.

Bug fixes:
- CAVLC level VLC encoding overflow for large coefficients (QP=0)
- Encoder reconstruction order (inverse Hadamard before dequant)
- SMPTE bars distributed at block-column granularity in -8x8 mode
- CLI -8x8 flag takes priority over .gridimg default block size
