Replace broken Pulsedive example with real console export

Retires ioc-analysis-pulsedive.yaml — it failed server-side API validation (a cs.json.decode over Inline.Python output_stdout, which release rejects) and carried stale synthetic parallel-join nodes from an older converter. Replaces it with domain-enrichment-pulsedive.yaml, a Falcon console export (Content Library playbook 8746f79b2514435db58f433fa062a4ee) that passes validate.py at all tiers.

The new example is the fan-out -> converge reference: parallel Pulsedive lookups store their real response objects into WorkflowCustomVariable (indicator_details_result, explore_indicators_result) via UpdateVariable, read by downstream comment/tag actions. Repoints the http-actions.md and README citations to it with accurate variable names.

Also refreshes the Inline.Python reference: the deleted file was its 'Full example', so the reference now carries an inline abuse.ch SSL-blocklist parsing snippet (CEL++ use case: fetch + parse a feed for a lookup file) and notes a console-verified end-to-end example is in progress. Every shipped example now passes server-side API validation.
