fix: compilation errors, deprecation warnings, and add unit tests (#17)

- Fix WeakPoint struct initializations missing `file` and `line` fields
  across src/kanren/core.rs, src/a2ml/mod.rs, and all test files
- Migrate report/gui.rs from deprecated egui API (TopBottomPanel,
  SidePanel, CentralPanel::show, ScrollArea::id_source) to current
  Panel::top/left/show_inside and id_salt
- Fix version mismatch: main.rs command version now matches Cargo.toml
  (2.1.0)
- Fix stale repository URL in Cargo.toml (panic-attacker → panic-attack)
- Add `log` crate and replace raw println!/eprintln! with structured
  logging in groove.rs, kanren/rules.rs, assail/analyzer.rs, notify.rs,
  ambush/mod.rs
- Remove useless usize >= 0 comparisons in property_tests.rs
- Add 11 unit tests for assail/analyzer.rs covering language detection,
  unsafe code detection, panic path thresholds, command injection, eval
  detection, empty directory handling, and excluded directory skipping
- Add 13 unit tests for panll/mod.rs covering axis/category labels,
  export format, image/temporal diff serialization, and write_export I/O

All 381 tests pass with zero warnings.
