feat: rebrand as Hermit — TUI palette, dual glyphs, binary 0.10.0

"""Batch-convert icons/agent-motion SVG states into a color emoji-style font.
|
||||
|
||||
Outputs:
|
||||
res/hermit-icons.ttf (CBDT/CBLC bitmap glyphs when fonttools works)
|
||||
.gen/hermit_font_map.inc (PUA codepoint table for the TUI)
|
||||
|
||||
PUA layout matches cst_hermit_glyph.h:
|
||||
U+E700 + (shell * N_STATE + state) * N_FRAME + frame
|
||||
|
||||
Requires (optional): rsvg-convert or cairosvg, pillow, fonttools.
|
||||
Without them, still writes hermit_font_map.inc so FONT mode can emit codepoints.
