Introduce a hash of Chromium sandbox interface files to detect incompatibilities between bootstrap.exe and libcef.dll at runtime, allowing the strict version check to be skipped when interfaces match. Core implementation: - Add sandbox_compat_hash.py to calculate SHA-256 of interface files (chrome_elf_main.h, sandbox.h, sandbox_types.h, sandbox.mojom) - Update make_version_header.py to generate CEF_SANDBOX_COMPAT_HASH - Add sandbox_compat_hash field to cef_version_info_t struct - Add entry 3 to cef_api_hash() for retrieving the hash - Compare hashes in cef_scoped_library_loader_win.cc during load Version management: - Include sandbox_compat in cef_api_versions.json and cef_api_untracked.json - Compare sandbox_compat for untracked versions (NEXT, EXPERIMENTAL) - Trigger version bumps when sandbox interface files change Build automation: - Update cefbuilds JSON builder to include sandbox_compat in version records - Run version_manager.py -a after Chromium updates on release branches to auto-detect hash changes and add new API versions
