Relink 0.19.0

This release improves loading and symbol lookup, adds optional transparent huge pages, and simplifies runtime ownership.

Highlights

• Added configurable transparent huge page (THP) support for file-backed mappings, copied segments, and BSS.
• Reduced allocations and redundant work in loading, symbol lookup, and dependency linking.
• Improved TLS caching and thread-exit cleanup.
• Added host::main_search() to read dependency search paths from the main executable.
• Fixed relocation edge cases and tightened module ownership checks.
• Updated benchmarks with real libraries and Clang / LLVM workloads, and simplified documentation and examples.

Breaking Changes

• Unified module exports through ExportTable and mapping configuration through SpaceLayout and SpaceInit.
• std and use-syscall are now mutually exclusive.
• Scanning now uses LoaderRun::scan.
• SearchPathResolver::with_config now takes main-executable search metadata.
• Custom mapping, relocation, observer, and TLS implementations may require updates.
