Allow users to persist default flag values in a YAML config file at ~/.fleet-e2e-toy.yaml so they don't have to repeat common flags on every run.
Acceptance Criteria
- Tool reads
~/.fleet-e2e-toy.yaml on startup if it exists
- CLI flags override config file values
- If the file has unknown keys, a warning is printed but the tool continues
- Document the supported config keys in the README
