Part of #183, phase 2. Blocked on #184.
- Add
~/.toolpath/config.toml as a figment layer below env.
- Precedence: defaults < toml < env < flags.
- Decide which settings are file-worthy. Document them.
- Constraint: the file lives inside the config dir, so a toml key can not set the config dir location. Root relocation stays env/flag only.
