chore(release): bump to 10.0.2

[branarakic]

Version bump 10.0.1 → 10.0.2 (root umbrella + all 19 packages; dkg-okf aligned rc.16 → 10.0.2 for its first stable publish) + the 10.0.2 CHANGELOG entry. Baseline for tagging v10.0.2.

🌟 Highlight — Google Open Knowledge Format (OKF) support (#1388)

The DKG can now turn a portable Google Open Knowledge Format bundle — Markdown + YAML frontmatter + untyped cross-links — into owned, cryptographically-provenanced RDF Knowledge Assets, and serialise a Context Graph cleanly back out to a conformant bundle.

OKF standardises how knowledge is written and exchanged, but ships no verification, provenance or ownership layer. The new @origintrail-official/dkg-okf package is the bridge that adds all three — deterministic and offline (no LLM, no network): the same bundle always yields identical triples and IRIs.

dkg okf import ./bundle --dry-run --print-nquads          # deterministic preview, never touches a node
dkg okf import ./bundle --context-graph-id my-graph --share   # import → Shared Working Memory
dkg okf verify my-graph ./bundle                          # per-predicate integrity gate
dkg okf export my-graph ./out                             # clean inverse → conformant OKF bundle

Also in 10.0.2 (fixes & improvements)

• PCA agent & operational-wallet management — bulk registerAgents in one tx (feat(evm): bulk registerAgents — add many PCA agents in one tx #1387), agents preserved on PCA transfer (feat(evm): preserve PCA agent allow-list across NFT transfer (OT-RFC-51) #1384), and a Node UI Admin page for operational wallets / PCAs / agent keys via wallet-connect (feat(node-ui): Admin page — operational wallets, PCAs, agent keys + wallet-connect #1370).
• Context-Graph registration deposit waiver (feat(evm): PCA-backed CG registration-deposit waiver — quota-bounded (OT-RFC-53) #1366) — anti-spam CG deposit with a waiver for accounts holding a sufficient active PublishingConviction commitment.
• Backend-independent V10 leaf canonicalization (fix(core): backend-independent V10 merkle leaf term canonicalization #1386, fix(core): backend-independent V10 leaf canon — xsd:dateTime/time (OT-RFC-57, Tactical) #1399) — nodes running any SPARQL 1.1 store (Oxigraph, Blazegraph, …) now compute identical merkle leaves, so Random Sampling no longer depends on a node's store backend. Validated against a live cross-backend oracle + a mixed-backend devnet.
• Sub-graph Random Sampling extraction (fix(random-sampling): make RS proof extraction sub-graph aware (#1367) #1385) — a KA published into a named sub-graph is now extractable and provable.
• Node UI (fix(node-ui): hide the Admin page entry point (icon + /admin route) #1391) — hide the Admin page entry point by default.
• Devnet coverage (test(devnet): network-level coverage for the 10.0.2 merged PRs #1397) — network-level test suites for all of the above.
