# Dockerfile.dev — local-development image with air-driven live reload.
#
# Selected by docker-compose.dev.yml (overlay over docker-compose.yml).
# Production stays on workspace-server/Dockerfile (static binary, no air).
#
# Workflow:
#   1. docker compose -f docker-compose.yml -f docker-compose.dev.yml up
#   2. Edit any .go file under workspace-server/
#   3. air detects, rebuilds, kills old binary, starts new one (~3-5s)
#   4. No `docker compose up --build` needed
#
# Templates + plugins are NOT pre-cloned here — air-mode assumes the
# developer's filesystem has the workspace-configs-templates/ + plugins/
# dirs available, mounted at runtime via docker-compose.dev.yml.
