Issues #3 and #4.
Remove:
- CATEGORY_NAMES dict (170 Kindred-specific category codes)
- sanitize_filename(), parse_part_number(), get_category_folder_name()
- import re (only used by removed sanitize_filename)
These are consumer-side concerns (filesystem path construction) that
don't belong in a generic HTTP client. Categories should be fetched
dynamically from the server via the schema API.
Add schema methods:
- list_schemas() — GET /api/schemas
- get_schema_form(name) — GET /api/schemas/{name}/form
- add_enum_value(schema, segment, code, label) — POST enum value
- update_enum_value(schema, segment, code, **fields) — PUT enum value
- delete_enum_value(schema, segment, code) — DELETE enum value
Bump version 0.1.0 -> 0.2.0.
