Subject: feat: parse hyprsunset.conf profiles

Implement minimal config parser with Profile dataclass and parse_config function.
Regex-based parsing of hyprsunset.conf format with support for time, identity,
temperature, and gamma fields. Foundation for later tasks (serialize, read/write, validation).
