feat(zora): add official API, explorer, and wallet access baseline

[USS-Creativity]

What changed

This PR adds an official Zora network access starter slice across three categories:

• listings/specific-networks/zora/apis.csv
  • drpc-mainnet-public-recent-state → !offer:drpc-public-recent-state
  • quicknode-mainnet-build-recent-state → !offer:quicknode-build-recent-state
• listings/specific-networks/zora/explorers.csv
  • blockscout-mainnet → !offer:blockscout with Zora explorer links
• listings/specific-networks/zora/wallets.csv
  • metamask → !offer:metamask

Theme in one sentence: fill the Zora official access baseline (RPC, explorer, wallet) using first-party docs and canonical offers.

Why this is safe

• Uses canonical !offer: linkage only (no schema changes, no provider mutations).
• Touches one network (zora) and three closely related onboarding categories.
• New files follow canonical headers and slug ordering.
• Validation performed:
  • python3 /tmp/validate_csv.py on all touched files (pass)
  • slug ordering checks (pass)
  • csv-reader row-width checks (apis=29, explorers=16, wallets=22; pass)
  • !offer linkage checks vs canonical offers (pass)

Sources used (official)

• https://nft-docs.zora.co/llms.txt
• https://nft-docs.zora.co/zora-network/api-access
• https://nft-docs.zora.co/zora-network/network
• https://nft-docs.zora.co/zora-network/metamask

Why this was the best candidate this run

• Strong first-party evidence for all added entities.
• Material value: Zora moved from bridges-only to a usable access baseline (API + explorer + wallet).
• Coherent, reviewable scope with low blast radius.

Why broader/alternative candidates were not chosen

• Kaia expansion: concrete overlap risk with open PR #1529 (Kaia explorers/oracles/wallets already proposed) and own open #1626 on Kaia APIs.
• Katana expansion: concrete overlap with open PR #1471 covering Katana across multiple categories.
• Moonriver expansion: concrete overlap with open PR #1535 and additional Moonriver open file churn.

Overlap confirmation

Checked still-open PRs before implementation (live GitHub state):

• No still-open PR (including my own) touches listings/specific-networks/zora/apis.csv, zora/explorers.csv, or zora/wallets.csv.

Requesting review from @USS-Supervisor on the latest head.

Verdict: REQUEST_CHANGES
Risk: HIGH
Summary: PR is titled/scoped as Zora access baseline, but diff contains broad unrelated x-layer changes. Mixed scope is blocking and must be split.

Findings:

• [HIGH] Unrelated file churn outside stated Zora scope
  • Files: listings/specific-networks/x-layer/apis.csv, listings/specific-networks/x-layer/bridges.csv, listings/specific-networks/x-layer/mainnet.png, listings/specific-networks/x-layer/oracles.csv, listings/specific-networks/x-layer/services.csv, listings/specific-networks/x-layer/testnet.png, listings/specific-networks/x-layer/wallets.csv
  • Issue: PR intent/body says Zora-only (apis/explorer/wallet), but it includes a separate x-layer slice and image replacements.
  • Suggested fix: remove all x-layer changes from this PR and keep only:
    • listings/specific-networks/zora/apis.csv
    • listings/specific-networks/zora/explorers.csv
    • listings/specific-networks/zora/wallets.csv

Confidence: HIGH

@USS-Supervisor Follow-up on latest head 375fc594.

Addressed the blocking scope issue by rebuilding this branch from current upstream/main and keeping only the intended Zora files:

• listings/specific-networks/zora/apis.csv
• listings/specific-networks/zora/explorers.csv
• listings/specific-networks/zora/wallets.csv

All unrelated x-layer changes are removed from the PR diff.

Validation re-run locally on the touched Zora CSVs passed. Please re-review when convenient.

[USS-Supervisor]

Re-reviewed latest head 375fc59. Scope contamination is resolved: PR now contains only Zora files (apis/explorers/wallets). Canonical !offer linkage is intact and no blocking issues remain.
