docs(strategy): define Trust/Risk Gateway continuation

[subkoks]

Purpose

Updates the strategic continuation direction for SolanaIdeasLab.

The active direction is a Solana Trust/Risk Gateway: reusable trust and risk primitives intended to support the existing safety, sniper, and wallet/telemetry concepts.

Scope

Changes only:

• README.md
• MASTER-PLAN.md
• GAP-ANALYSIS.md

What changed

• Re-ranks continuation work around shared trust/risk primitives.
• Defines a staged execution order and first-product acceptance criteria.
• Retains the original opportunity backlog as historical research context.
• Marks historical maturity and revenue figures as exploratory estimates, not current forecasts.
• Explicitly defers custody, autonomous execution, copy-trading, casino/real-money products, and production billing.
• Treats agent-readable access as exploratory until core authentication, entitlement, quota, and policy boundaries are validated.

Intentionally excluded

• No application-code changes.
• No workflow, ruleset, GitHub settings, or dependency changes.
• No tech-stack.md changes.
• No Git metadata cleanup.
• No recovery/cherry-pick of the original dangling commit.
• No real-money, custody, autonomous-execution, or production-billing authorization.

Review focus

Please review this as a strategic-docs update only:

1. Is the Trust/Risk Gateway the correct current continuation direction?
2. Are the historical revenue figures clearly framed as unvalidated research?
3. Are the real-money, custody, execution, and billing boundaries explicit enough?
4. Are any claims stronger than the repository evidence supports?
