refactor: improve code quality and consistency

- parser.go: compile regex once at package level (perf)
- parser.go: include response body in HTTP error messages (debug)
- main.go: use strings.HasPrefix for URI detection (safety)
- html.go: handle file close errors consistently
- docx.go: extract font size magic numbers to constants
- markdown.go: normalize item types to lowercase for consistency
