PHLEGM v8 checkpoint 67: data-driven vector identities

Canonical format: cfg/instructions/<$project>.bezier.phlegm
Resolved name for PHLEGM: cfg/instructions/PHLEGM.bezier.phlegm
Project substitution: cfg/PHLEGM.master.phlegm internal.name -> <$project>.
Instruction file naming: <$project>.cmd/.console/.gui.phlegm.

Contents: cubic Bezier vector paths for folder, Up/Back (two dot),
PRG/CART, chipset/support chip, CHR bank, firmware, console, document,
and all eight ZIP folder-plus-conditional-cutout variants.
Paths, palettes, icon drawing order, aliases, and existing numeric kind
mappings are declared in the new text definition.

The shipped icons.lib still renders its built-in versions; the vector
file is a forward-compatible data definition, not a runtime renderer.
No bezier.lib is needed for declaration; a reusable generic library
could later supply parsing, cubic evaluation, and platform-independent
path traversal while icons.lib retains bitmap caching.

No Python files or tools are packaged with the distribution.
