docs(citation): add CITATION.cff with the author's ORCID (0000-0002-3078-6652)

[hyperpolymath]

Adds the author's ORCID iD, 0000-0002-3078-6652, to this repo's citation metadata.

• CITATION.cff: created

Part of an estate-wide rollout. The template's own 0000-0000 placeholder is fixed at source in hyperpolymath/rsr-template-repo#214. No licence fields were added or changed.

1-29: LGTM!

Both findings were fixed in 3969b39: the title is now ECHIDNA, matching the README, and the abstract no longer gives a count, so it cannot drift from docs/PROVER_COUNT.adoc. CodeRabbit acknowledged the title fix in-thread but did not re-review, because its hourly allowance was exhausted.
