- Box ZlError::ElfAnalysis to eliminate 121 result_large_err warnings
- Remove 7 dead ZlError variants (Database, Network, PathRemap, etc.)
- Add AppContext struct to bundle shared state, replacing 8-10 param functions
- Fix all clippy warnings (225 → 0): collapsible_if, for_kv_map, dead_code, etc.
- Fix real bug in remap_shebang() that prevented shebangs from ever being remapped
- Add 32 new tests (154 → 186): core/elf/analysis, core/path, core/path/remapper
- Add GitHub Actions CI workflow (fmt + clippy -D warnings + test)
- Update CLAUDE.md to reflect current state

…e cascade, better errors

Major improvements to search, install, remove, and error handling:

Search (`zl search`):
- Parallel queries across all plugins via thread::scope
- Relevance scoring: exact(100), starts-with(80), contains(60), desc(30)
- New flags: --sort (relevance|name|version), --exact
- Result count per source, truncated descriptions, tag annotations

Install (`zl install`):
- Universal source picker queries ALL plugins in parallel
- AUR -bin/-appimage/-prebuilt variants auto-discovered and offered
- Clear labeling: [binary], [source], [release] tags in picker
- Architecture compatibility check on ELF binaries before patching
- Post-install missing shared library warnings

AUR plugin:
- Binary variant discovery: searches for -bin/-appimage/-prebuilt
- [binary] tag in descriptions for precompiled packages
- Better build error messages with specific hints (base-devel, PGP)
- Captures stderr from git/makepkg for actionable error output

Remove (`zl remove --cascade`):
- Preview what cascade will/won't remove before prompting
- Shows "Keeping X (needed by Y)" for shared dependencies
- Dry-run support shows full removal plan
- Only removes ZL-managed implicit dependencies, never system pkgs

Error handling:
- Plugin-specific suggestions: pacman mirrors, APT repos, GitHub
  rate limits, AUR build deps, arch mismatches, self-update perms
- New ArchMismatch error variant
- elf_machine_to_arch() + check_arch_compat() in ELF analysis

195 tests pass (103 bin + 92 lib), zero clippy warnings, zero fmt diff.

- Feature branches only, never work on main directly
- Branch naming: feat/, fix/, chore/, refactor/, docs/
- Merge only when CI passes, delete branch after
- Atomic commits: 1 commit = 1 concept
- Commit format: type: title + bullet points
- Documentation: update CLAUDE.md + README.md after changes
