Missing Transaction Query APIs & Clarification on Cross-Action Revert Behavior

[Chocolatieee0929]

Description:

While working with Vert, I encountered two unresolved questions regarding EOS transaction handling:

1. Transaction Query API Gap
   Currently, I cannot find exposed methods in the Vert SDK to:
   • Retrieve transaction details by ID (e.g., getTransactionById)
   • Access blockchain transaction history via blockchain structure (e.g., blockchain.transactions)
   This makes it impossible to programmatically verify transaction finality or inspect post-execution states.

2. Cross-Action Revert Behavior
   From EOS documentation, when a primary action triggers on_notify actions as separate transactions, I want to confirm:
   • If an on_notify action reverts, does it cascade to revert the primary action?
   • How to trace transaction dependency chains in Vert (e.g., parent-child TX relationships)?
