fix: SSH accept-new and DOMAIN_SUFFIX configuration for edge control
- Changed SSH StrictHostKeyChecking from 'no' to 'accept-new' for better security
- Fixed .env write logic with proper deduplication before appending
- Fixed deregister .env cleanup to use single grep pattern
- Added --domain-suffix option to install.sh
- Removed no-op DOMAIN_SUFFIX sed from install.sh
- Changed cp -n to cp for idempotent script updates
- Fixed authorized_keys.sh SCRIPT_DIR to point to lib/
- Fixed Caddy route management to use POST /routes instead of /load
- Fixed Caddy remove_route to find route by host match, not hardcoded index

# lib/caddy.sh — Caddy admin API wrapper
#
# Interacts with Caddy admin API on 127.0.0.1:2019 to:
# - Add site blocks for <project>.disinto.ai → reverse_proxy 127.0.0.1:<port>
# - Remove site blocks when deregistering
#
# Functions:
# add_route <project> <port> → adds Caddy site block
# remove_route <project> → removes Caddy site block
# reload_caddy → sends POST /reload to apply changes
