chore(examples): regenerate the demo holon samples through xbrlkit

[jfrench9]

Summary

Follow-up to #1373. The other four tracked .holon.jsonld samples were still the old partition's output — each missing 52–59 element declarations for the rows its arcs reach. Regenerated offline from the flat JSON-LD beside each, through write_holon_jsonld (the DataBook converter), the same path the SaaS sample took in #1373. No code change.

sample	undeclared endpoints before	after	concepts / labelled
coffee-roaster-demo	56	0	101 / 93
roboledger-demo	59	0	93 / 93
seattle-method-case-1	52	0	93 / 93
world-online	58	0	93 / 93

Each file loads in xbrlkit with the report id as its accession; facts are unchanged.

Review: chore/holon-samples-regen

• Gather context (PR body, diff stat, prior PR fix(serialization): emit the holon from xbrlkit through the bundle bridge #1373)
• Inspect the 4 regenerated .holon.jsonld files for structural validity and consistency
• Verify claims in PR description (undeclared endpoints resolved, concepts/labelled counts)
• Check for any code changes (should be none per description)
• Post review feedback

Scope confirmed: only the 4 sample files changed (git diff origin/main...HEAD --stat), no code touched.

Verified independently (parsed all 4 files with jq, diffed against origin/main):

sample	valid JSON	undeclared from/to endpoints	concepts (distinct rs:Element)	unlabelled concepts	fact content unchanged
coffee-roaster-demo	✅	0	101	8 (→ 93 labelled, matches PR table)	✅ identical
roboledger-demo	✅	0	93	0	✅ identical
seattle-method-case-1	✅	0	93	0	✅ identical
world-online	✅	0	93	0	✅ identical

• The "undeclared endpoints" fix checks out: cross-referencing every rs:Association.from/.to against declared rs:Element nodes yields zero unresolved refs in all four files, vs. the 52–59 gaps described pre-regen.
• "Facts are unchanged" also checks out: diffing {element, numericValue, decimals, factType} for every rs:Fact (sorted, ignoring internal reference IDs) against the pre-regen files shows byte-identical content in all four samples.
• The only diff in fact nodes themselves is internal reference plumbing (period/unit/factSet now use content-addressed hash IDs, structure dropped from facts, factSet can be an array) — this matches the shape already present in examples/saas_startup_demo/sample_output/saas-startup-demo.holon.jsonld (regenerated in fix(serialization): emit the holon from xbrlkit through the bundle bridge #1373 and already merged), so it's consistent with the converter's current schema rather than a regression introduced here.
• Report accessionNumber is present and distinct per sample, consistent with the "loads with the report id as its accession" claim.

No issues found. This is a clean, verifiable data-only regeneration — approving from a correctness standpoint.

Closing: these were regenerated through the DataBook reader path, not downloaded from the API like every other sample, so their period/unit ids differ from the flat JSON-LD beside them. The samples come back as a full re-download once the bridge passes structure and fact-set ids through to xbrlkit (follow-up in progress).
