Summary

Adds one shared SC2AIOptimize integration compatibility authority for bot consumers instead of duplicating connector logic per bot.

• bumps the additive public API contract from 1.0 to 1.1
• adds IntegrationContract.hpp for API/UnitView ABI/registry/capability handshake
• exposes the same authority through the stable C ABI and Python binding
• adds explicit C++14 -> C ABI consumer proof for older native bots such as MMEvo
• preserves baseline/OFF semantics on compatibility rejection
• documents that missing-library/module fallback is a consumer packaging/loading responsibility
• keeps bot/framework policy and types outside SC2AIOptimize

Intended integration

• MMEvo can consume the stable C ABI without adopting SC2AIOptimize's C++20 public headers.
• Future MetaSwarm MSAPIOpt can consume the Python edge from the same compatibility authority.
• This PR does not implement MSAPIOpt runtime integration or change bot gameplay.

Proof

Existing CI exercises Windows/Linux core, Python, C ABI, sanitizers, static analysis, installed consumer and ISA gates. This PR adds compatibility-contract tests and a C++14 C-ABI consumer target to the existing C-ABI matrix.
