adlee-was-taken	ef5a9ce9cb	Add per-channel hybrid audio spread spectrum and env feature toggles ... Spread spectrum v2: independent per-channel embedding with round-robin bit distribution, preserving spatial stereo/surround mix. Adaptive chip tiers (256/512/1024) trade capacity for lossy codec robustness. LFE channel skipped for 5.1+ layouts. v2 header (20B) with backward- compatible v0 decode fallback. Environment toggles (STEGASOO_AUDIO, STEGASOO_VIDEO) gate audio/video features for minimal builds (e.g. Raspberry Pi image-only). Values: auto (default, detect deps), 1/true (force on), 0/false (force off). Web UI fixes: accordion defaults to step 1 on load, chevron arrow styling, required attribute toggling for audio carrier type switch, "Images & Mode" renamed to "Reference, Carrier, Mode".

Aaron D. Lee	34ede3815f	Add API key authentication and TLS support ... API Authentication (v4.2.1): - API key auth via X-API-Key header - Keys hashed (SHA-256) and stored in ~/.stegasoo/api_keys.json - Auth disabled when no keys configured - Protected endpoints: encode, decode, generate, channel/*, compare, etc. - Public endpoints: /, /docs, /modes, /auth/status, /channel/status TLS Support: - Auto-generates self-signed certs on first run - Certs include localhost, local IPs, hostname.local - Stored in ~/.stegasoo/certs/ CLI Commands: - stegasoo api keys list/create/delete - stegasoo api tls generate/info - stegasoo api serve (starts with TLS by default) Updated systemd service to use TLS.
