This PR adds a developer-oriented document for the Fast Token Delivery implementation.
The document explains the overall FTD flow and focuses on the suppression machinery in
FtdSuppression, including:local CFG construction and decision graphs
loop decomposition into acyclic layers
path enumeration and Boolean condition construction
BDD-to-mux lowering
condition-token distribution
token demotion across loop levels
the
insertDirectSuppressiondriverreuse for loop back-edge conditions
regeneration and GSA gate conversion
condition placeholders and FTD annotation attributes
The goal is to make the current implementation easier to understand, debug, and maintain, especially the parts that ensure the generated suppression circuits satisfy the token-matching invariants.
