Add opt-in localpoc profile for the local highlight PoC

Activated with --spring.profiles.active=localpoc. Points only at pre-provisioned
local model paths (Piper voice, MusicGen, AudioLDM2), disables bootstrap
auto-start, uses heuristic visual analysis, isolates PoC input/output dirs, and
keeps render disabled + director approval required. Base/production defaults are
untouched.

+# starts a network-capable bootstrap script.

+# Prohibitions still in force: no rendering without an explicit approved.flag for the specific project,
+# no external AI, no placeholder audio. Models load offline from models/ (the worker sets HF_HUB_OFFLINE).
