Pull request overview

Release v2.9.0 merge-back introducing the Valencia hardfork activation across configs and adding several safety/performance hardening changes in RPC execution, witness serving, and Bor state-sync handling.

Changes:

• Wire up ValenciaBlock (Amoy 40,776,000, Mainnet 89,531,000) across runtime presets, CLI chain presets, genesis files, forkid, and config banner/tests.
• Add Valencia+ state-sync size budgeting and miner-side block-size reservation to prevent oversized/non-propagating sprint-start blocks.
• Harden RPC and WIT: replace RPC workerpool with a semaphore-based limiter (with tests), cap WIT request element counts, and add framing-aware response size checks / uncached witness reads; add singleflight for concurrent GetRootHash cache misses.
