feat(rules_score): add glossary support and example in SEOOC

[vishwajitdandage]

What

• New glossary artifact support in rules_score.
• SEOOC example now contains and builds a glossary document.
• Dependable element index/report generation includes glossary entries.
• Related SEOOC docs were updated to use glossary-backed terminology.

How

• Added a dedicated glossary rule in rules_score to expose glossary sources through SphinxSourcesInfo.
• Extended dependable_element to accept glossary inputs and include them in generated index content.
• Updated the index template to render a glossary section.
• Wired the SEOOC example to include glossary content and reference glossary terms from related docs.

NOTE:

Glossary support is optional

dependable elements can be defined without glossary inputs, and glossary content is included only when explicitly provided.
