Add native audio/image efferent surfaces + projector proof-of-shape

audio-surface.el / image-surface.el: own-core additive-synthesis WAV and
raster-PNG renderers (integer-only DSP, since EL has no floats), rendered
from learned engram signatures via a pluggable surface-profile
abstraction (surface-profile.el). audio-demo.el / image-demo.el are
drivers. NOTE: demo files hardcode absolute paths to this worktree's own
directory — will need a path fixup before landing.

elp/projector/ is a Python package the author's own README marks as
"STAGING/PROOF-OF-SHAPE — not the deliverable", superseded by the native
.el surface-profile work above; kept as a validated architecture proof.
Generated output (elp/faculty/{out,sig}, elp/projector/out,
__pycache__) intentionally excluded.

"""plan.py — PLAN stage: geometry region -> document skeleton (a DAG/outline).
The manifold becomes the skeleton. We extract faithful propositions from the
region's nodes (the proven neuron-talk extractor, SACRED polarity preserved),
apply a quality floor, then GROUP them into sections. Grouping is by source
node — each engram node is one coherent topic, so one salient node becomes one
section. The section ORDER is the node ranking (importance/salience): the
geometry decides the outline, not a template.
Output: a DocumentIR whose sections carry seed node ids and empty blocks. REALIZE
fills the blocks; the plan owns the structure.
