Fix url normalization (Uppercase URLs)

[jxxxxst]

Make wormpy work with uppercase URLs.

[jxxxxst]

Exclude unnecessary urls and metadata by default. Add flags to include them.

Default - minimal output for LLM context (no URLs, essential metadata only)
python main.py https://example.com

Include all discovered URLs
python main.py https://example.com --include-urls

Include all metadata fields
python main.py https://example.com --full-metadata

Include both URLs and all metadata (maximum verbosity)
python main.py https://example.com --include-urls --full-metadata
