data(providers): fill 43 verified contact and social fields on 28 providers

[EazyHood]

Fills contact and social fields that were empty on 28 provider rows: support email, docs, X, GitHub, Discord and Telegram. The final diff adds 43 non-null cells and does not overwrite or remove any value from current main.

Field breakdown:

• supportEmail: 19
• discord: 8
• telegram: 6
• github: 4
• x: 4
• docs: 2

Every value was read from the provider's own site, contact page, documentation, or official channel—not from an aggregator or third-party list. Where a provider does not publish a channel, the cell is deliberately left empty rather than guessed.

Collision and rebase audit:

• removed eight cells covered by earlier open contributions (data: fill 100 verified provider links (batch 3/3) #2978, data: fill 200 verified provider links (batch 2/3) #2979, data(somnia): refresh provider platform metadata #3130 and data: complete Gora MELD and Filecoin contacts #3131), including both conflicting Gora values
• rebased onto current main so newer merged provider metadata is preserved
• final comparison against current main contains 43 additions, zero modifications and zero removals

Validation:

• official json-tools validate_csv.py: All checks passed
• all providers.csv rows retain the 14-column schema

Verdict: APPROVE
Risk: MEDIUM
Summary: The broad provider metadata fill only updates previously blank provider contact/social/docs cells, does not add or remove rows, preserves the 14-column provider CSV shape, and the platform/contact formatting pass found no full-URL leakage in social fields or malformed contact values.
Findings: None.
Confidence: MEDIUM

Required validation passed on current head 42c245d, static CSV checks were clean, and the current-cycle link-check run 32548092553 reported 180 total links, 180 successful, and 0 errors/timeouts/unsupported URLs.
