v2.2.6

• Faster short and mid-sized encoding: processes digits in pairs and reuses fixed-width encoding helpers instead of dividing once per digit.
• Less work for large integers: replaces one full-width quotient calculation with bounded u64 arithmetic.
• Faster decoding: short inputs avoid wide arithmetic, and byte-indexed lookup tables simplify validation.
• Smaller decoder-only binaries: encoding tables can now be discarded by the linker. A local linkage probe was about 8 KiB smaller.
