fix(library): resolve named local dependencies

[zackees]

Closes #1256\n\nResolves named Name=symlink://... and Name=file://... dependencies relative to the project directory, adds their include directories, and keeps generated library objects/archives under fbuild's build directory rather than the source checkout. Includes Windows ile:///C:/... normalization and focused resolver/archive-path tests.\n\nValidation:\n- soldr cargo test -p fbuild-library named_local_symlink\n- soldr cargo test -p fbuild-library external_build_dir\n- soldr cargo test -p fbuild-library windows_file_uri\n- soldr cargo test -p fbuild-build-esp --no-run\n- Local FastLED est-emu compiled the ESP32 core and sketch with FastLED=symlink://../..; the local CLI request did not return after compilation, so the QEMU completion marker remains unverified.

Summary by CodeRabbit

• New Features

  • Added support for named local library dependencies using symlink:// and file:// paths.
  • Local libraries can now be resolved relative to the project and built in separate directories.
  • Improved handling of local library includes and Windows file paths.

• Bug Fixes

  • Corrected archive placement when libraries use an external build directory.

• Chores

  • Updated the project version to 2.5.12.

📝 Walkthrough

Walkthrough

The change adds named symlink:// and file:// local dependencies. Relative paths resolve from the project directory. Local libraries build under libs_dir, separate from their source directories. Package versions update to 2.5.12.

Changes

Local library resolution

Layer / File(s)	Summary
Local dependency parsing crates/fbuild-library/src/library/library_spec.rs, crates/fbuild-library/src/library/README.md	LibrarySpec stores named local paths and parses symlink:// and file:// dependencies. Tests cover invalid names, Windows paths, and unnamed local paths.
Separate build artifacts crates/fbuild-library/src/library/library_info.rs	InstalledLibrary supports a separate build_dir. Archive paths and compilation outputs use that directory.
Resolution and compilation integration crates/fbuild-library/src/library/library_manager.rs, crates/fbuild-build-esp/src/esp32/orchestrator/build.rs, Cargo.toml, pyproject.toml	Library resolution receives project_dir, stages local builds under libs_dir, and updates callers and tests. Package versions update to 2.5.12.
