update verify and testbench

[n0thingNoob]

Update verify file.

[Copilot]

Pull request overview

This PR generalizes the verification system from being histogram-specific to supporting multiple kernels (histogram, FIR, AXPY). It updates report messages, refactors test code to reduce duplication, adds environment variable support for program paths, updates default YAML file names, and incorporates changes from the Zeonica_Testbench submodule.

Changes:

• Generalized report messages by removing "histogram" references
• Refactored integration tests to use a shared fileExists helper and consolidated file existence checks
• Added ZEONICA_PROGRAM_YAML environment variable support across verify commands and testbench
• Updated core program structures to include CompiledII and IndexPerII fields from YAML
• Updated expected return value in FIR testbench from 12 to 10
