v0.15.0

[weizhiao]

Relink 0.15.0 is now available.

Release notes: https://github.com/weizhiao/Relink/releases/tag/v0.15.0

Highlights since 0.14.1:

• Added explicit Linker dependency-loading APIs with reusable LinkContext, resolver-driven DT_NEEDED handling, visible module scopes, observers, and relocation planning.
• Added SearchPathResolver for filesystem-backed dependency resolution, including DT_RUNPATH / DT_RPATH and $ORIGIN expansion.
• Added scan-first linking with LinkPipeline, typed pass scopes, section layout planning, section-region materialization, arena-backed runtime memory, and retained-relocation metadata rewriting.
• Added architecture-selected relocation domains and cross-architecture loading plumbing across loaded images, linker state, and relocation helpers.
• Added configurable loader page sizes, madvise plumbing, structured mmap advice, and more explicit platform backends.
• Added relocatable object loading support behind the object feature, centered on x86_64.
• Reworked relocation diagnostics with structured failure reasons and contextual errors.
• Reorganized ELF, image, loader, segment, relocation, TLS, and linker internals into smaller modules while preserving public entry points.
• Added synthetic module and retained module-scope handling for symbol lookup, lazy binding, and host symbol integration.
• Added examples for Linker::load and linker scan-first loading, refreshed README / README_zh, and added contribution guides.
• Expanded test coverage for dynamic relocations, lazy binding, TLS, object loading, scan-first planning, search-path resolution, borrowed mapped images, and generated ELF fixtures.
