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".

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

2d7fbd1e0d Add QR code generation to CLI and API 
CLI generate command:
- --qr <file.png|jpg> to save RSA key as QR image
- --qr-ascii to print ASCII QR code to terminal

API endpoints:
- POST /generate-key-qr - generate QR from key_pem
  - Supports png, jpg, and ascii output formats
  - Uses zstd compression by default
- Added has_qrcode_write to /capabilities

Core:
- generate_qr_code() now supports jpg/jpeg output format
- New generate_qr_ascii() for terminal display

01f0173dd4 Add EXIF Editor, consolidate channel key resolution 
EXIF Editor (Library → CLI → API → WebUI):
- src/stegasoo/utils.py: read_image_exif(), write_image_exif()
- CLI: stegasoo tools exif [--clear|--set Field=Value]
- API: /api/tools/exif, /api/tools/exif/update, /api/tools/exif/clear
- WebUI: EXIF Editor tab with inline editing, clear all, save/download

Architectural consolidation:
- Moved resolve_channel_key() to src/stegasoo/channel.py (was duplicated in 3 frontends)
- Added get_channel_response_info() for consistent API/WebUI responses
- Frontends now use thin wrappers that translate exceptions

DCT improvements:
- Added will_fit_by_mode() pre-check to WebUI encode (fail fast)
- Suggests LSB mode when DCT capacity exceeded

Dependencies:
- Added piexif>=1.1.0 for EXIF editing
