Pull Request Overview

Adds support for loading environment variables, headers, and secrets from a dotenv file and wires it into the CLI.

• Introduces a --dotenv[=PATH] flag and DotEnvInjector to merge .env entries into env, request headers, response headers, and secrets.
• Adds new CLI args: dotenv (optional path) and rsp_headers.
• Registers tempfile as a dev-dependency (presumably for future tests).

• Expand this doc comment to clarify that if no path is provided (e.g. --dotenv without value), it defaults to loading .env from the current directory.

• [nitpick] Consider using Option<PathBuf> with default_missing_value = ".env" instead of Option<Option<PathBuf>> for simpler parsing and a clearer API.

• [nitpick] The abbreviation rsp_headers may be unclear; consider renaming to response_headers (and EnvArgType::ResponseHeader) for consistency and readability.

rsp_headers: Option<Vec<(SmolStr, SmolStr)>>,

Cargo.toml:49

• You've added tempfile as a dev-dependency but no tests currently use it; consider adding tests for the dotenv logic or removing the unused dependency.

tempfile = "3.20.0"
