 feat(linux): add libpath package for finding native library paths (#4847) 
* feat(linux): add libpath package for finding native library paths

Add a new internal/libpath package that locates shared libraries (.so files)
on Linux systems. Supports multiple distributions and package managers.

Features:
- Multi-tier search: pkg-config -> ldconfig -> filesystem scanning
- Parallel search using goroutines for faster lookups
- Cached dynamic path discovery for Flatpak, Snap, and Nix
- Support for Debian/Ubuntu, Fedora/RHEL, Arch, openSUSE, NixOS
- Context-aware cancellation for graceful shutdown

Performance:
- Library found: ~1.4ms (parallel search)
- Library not found: ~46ms (was 84ms sequential)
- Cached path discovery: 14ns (was 15ms uncached)

* feat(libpath): add multi-library parallel search functions

Add functions to search for multiple library candidates in parallel:

- FindFirstLibrary: Search multiple libs in parallel, return first found
- FindFirstLibraryOrdered: Search in order of preference (for version priority)
- FindAllLibraries: Find all available libraries from a list

Useful when the exact library version is unknown, e.g.:
  match, _ := FindFirstLibrary("webkit2gtk-4.1", "webkit2gtk-4.0", "webkit2gtk-6.0")

Also adds findLibraryPathCtx for context-aware searching used by the
multi-library functions.

* refactor(libpath): split into separate files and fix race condition

Split libpath_linux.go into smaller, focused files:
- cache_linux.go: Path cache with thread-safe init/invalidate
- flatpak_linux.go: Flatpak runtime path discovery
- snap_linux.go: Snap package path discovery
- nix_linux.go: Nix/NixOS path discovery
- libpath_linux.go: Core search functions

Fixes:
- Fix data race between init() and invalidate() by holding mutex
  during cache writes inside sync.Once.Do (CodeRabbit review)
- Fix FindLibraryPathWithOptions not searching dynamic paths
  (Flatpak/Snap/Nix) - now uses GetAllLibPaths() (CodeRabbit review)
