chore(external docs): deduplicate codec/framing schemas in generated Cue docs

[thomasqueirozb]

Summary

The doc generator was inlining the full DeserializerConfig, SerializerConfig, and both FramingConfig schemas into every component Cue file that uses decoding, encoding, or framing. This meant adding a new codec variant touched every source or sink file instead of one place.

The generator now walks each component's resolved schema recursively, detects codec/framing schemas by structure (tag-field description text and decoder-only enum variants), extracts them into three shared files, and replaces them with small per-component Cue conjunctions that contribute only the per-component variation (required, default).

Shared definitions appear in decoders.cue, encoders.cue, and framing.cue; component files reference them with 2–4 line conjunctions instead of hundreds of inlined lines. Net: −23,741 lines across 67 component files.

How did you test this PR?

Ran make generate-component-docs and compared jq -S . website/data/docs.json before and after. The diff is nearly identical, with only the added definitions as a diff.
