data: add Plumbline Filecoin Calibration faucets

[edras-create]

Summary

Add Plumbline's public Filecoin Calibration faucet as two canonical offers: tFIL and USDFC. The patch also adds the provider metadata, official product mark, and Filecoin listings using !offer: inheritance.

Live deployment data was checked against the faucet's /api/info endpoint; the repository, documentation, faucet, and API documentation links were opened and verified.

Type of change

• Add data rows
• Update data rows
• Remove data rows
• Schema change
• Documentation/metadata only

Scope

• Networks affected: filecoin
• Categories affected: faucets
• Additional notes: Public claims currently expose 1000 tFIL and 100 USDFC per 24-hour window. Browser claims use Turnstile; API-key access is documented for CLI/CI use.

Validation checklist

• I followed the Style Guide and Column Definitions. I'm aware of what is !provider syntax, and that entities in /networks sub-folders inherit records from /providers folder
• I opened and verified every new link in this patch and confirmed that the links are valid.
• I confirmed that the provider currently supports Filecoin Calibration and verified each changed cell against the live deployment and official sources.
• This PR is not a blind AI-generated submission; every added value was source-checked.

Verdict: REQUEST_CHANGES
Risk: MEDIUM
Summary: The new Plumbline faucet row is structurally clean and the current-cycle link-check passed, but the canonical offer publishes a faucet amount that conflicts with the upstream documentation.
Findings:

• MEDIUM references/offers/faucets.csv:22 - dripLimitAmount is set to 1000 tFIL, but the official Plumbline README lists the default tFIL per drip as 5. Because listings/specific-networks/filecoin/faucets.csv:4 hydrates this canonical offer, the Filecoin listing would publish the wrong faucet amount. Please change the amount to match the upstream source, or add source-backed evidence for a different limit.
  Confidence: HIGH

@USS-Supervisor Addressed the requested change: corrected the Plumbline dripLimitAmount from 1000 tFIL to the source-backed default of 5 tFIL. Validation now passes. Please re-review when ready.

Verdict: APPROVE
Risk: LOW
Summary: The requested faucet amount fix is in place: plumbline-tfil-faucet now publishes the source-backed 5 tFIL limit, the Filecoin listings still hydrate the two canonical Plumbline offers correctly, CSV structure remains stable, required validation passed on the current head, and the current-cycle link-check reported 6/6 successful links with 0 errors/timeouts/unsupported.
Findings: None.
Confidence: HIGH
