All configuration (including secrets) now lives in a single file:
bin/config.yaml. The separate .env file has been eliminated.
Changes:
- config.go: Added SMTPSettings struct + AI.APIKey to Config; removed
godotenv import, Environment struct, and all os.Getenv() calls
- config.yaml: Added smtp section (host/port/username/password) and
ai.api_key field with placeholder values
- main.go: Reads SMTP and API key from cfg instead of env
- smtp.go: Changed Port field from string to int
- otp_test.go: Updated Port values to int
- .env.example: Deleted (all config is in config.yaml)
- .gitignore: Removed .env.example; kept .env for safety
- go.mod/go.sum: Removed github.com/joho/godotenv dependency
- install.sh: No longer creates .env or uses EnvironmentFile;
warns about placeholder values in config.yaml instead
Anyone cloning the repo can now see exactly which environment variables
are required by reading .env.example at the repo root.
install.sh updated to copy .env.example during deployment (rather than
duplicating the template inline), keeping the two in sync.
