Detailed Description

Type handler - encapsulates all 4 operations for one option type.

Each operation is a stage in the config parsing pipeline:

1. Extract: TOML datum → intermediate (value_str, int_val, etc)
2. Parse: intermediate → validated parsed value
3. Write: parsed value → struct field
4. Format: struct field → TOML output string

Type handler - encapsulates all 4 operations for one option type

Function pointers for TOML extraction, validation, writing to options struct, and formatting output for each option type (bool, int, string, double).
