fix(tools): identity audit exemptions + import hierarchy (#69 #70)

Browse Source 
#69: audit-theme-design tags hue/CVD/ANSI-family noise on white,
vantablack, lumon, hackerman, matte-black, miasma as [identity] with a
legend — do not retune identity palettes into traffic lights.

#70: import-palettes keeps surface≠overlay when color0==color8, derives
light UI chips from base (ANSI-black trap), gentler light mantle; roles
are first-class. No bulk re-import of shipped theme JSON.

Verified: V0 (py_compile + synthetic import fixtures + audit report).

Reports (never fails): OKLCH lightness architecture, extended WCAG
contrast pairs, hue-family sanity for status colors, accent harmony,
CVD (protanopia/deuteranopia) distinguishability, ANSI slot semantics.
Identity exemptions (#69): white, vantablack, lumon, hackerman,
matte-black, miasma deliberately reject traffic-light status hues.
Their hue / CVD / ANSI-family findings are tagged [identity] (expected
design noise), not bugs to "fix" into red/yellow/green.

Hierarchy vs ANSI (#70):
Nomarchy roles (surface/overlay/mantle/…) are first-class and may
diverge from ansi[0]/ansi[8]. When color0==color8 (gruvbox, everforest,
many light themes' black==bright-black), do NOT collapse surface and
overlay — derive a raised step so the bg stack has hierarchy.
Light themes: ANSI color0 is almost always "black" (dark), not a UI
chip. Using it as surface paints sludge on a light canvas — detect
that trap and derive surface/overlay from base instead.
After import, hand-tune roles if needed. Do not bulk-reimport shipped
themes/*.json without a hierarchy pass — this tool is for *future*
imports / new palettes.
