evm-oracle-state v0.3.0-alpha.2

This is the supported alpha for the opt-in pending oracle update channel. It lets searchers simulate oracle-dependent actions before a candidate transaction lands while keeping speculative updates completely separate from confirmed oracle state and reconciliation.

Highlights:

• Reuses the feeds already registered through OracleRuntime; no second feed subscription is required.
• Decodes Chainlink OCR2 direct, secondary, and forwarded transmissions with signed-envelope validation, deduplication, and committed-log correlation.
• Includes Ethereum mainnet sources for Alchemy full pending transactions and Flashbots MEV-Share behind explicit feature gates.
• Exposes transaction hashes, calldata, ordering material, proposed values, source observations, and lifecycle outcomes for downstream simulation and bundle construction.
• Adds public adapter, source, transport-identity, and chain-configuration seams for future oracle families and networks.
• Corrects the transport-test feature gate found during the hosted isolated-feature release check; all eight isolated features and the complete Rust 1.88 validation job are green.

Current scope and limitations:

• Experimental and disabled by default.
• Built-in presets are Ethereum mainnet only; other chains require explicit custom configuration and a compatible source.
• The built-in decoder covers registered Chainlink OCR2 feeds only.
• Pending visibility is best effort and never guarantees completeness, inclusion, success, or sufficient lead time.
• The crate observes and classifies candidates; it does not simulate strategies, sign transactions, or submit bundles.
