refactor: add display modes to `RuntimeStatsDisplay`

Add three display modes for runtime statistics: Compact (default single-line),
Multiline (one item per line), and HumanReadable (formatted tables with
`tabled` crate). The human-readable mode uses rounded table borders,
right-aligned numbers, and thousand separators for better readability.

Changes:
- Add `DisplayMode` enum with `Compact`, `Multiline`, `HumanReadable` variants
- Add mode switching methods: `compact()`, `multiline()`, `human_readable()`
- Add `tabled` dependency for table formatting (optional, with `runtime-stats` feature)
- Update benchmark to use `multiline()` for periodic stats and `human_readable()` for final stats

Example output:

Multiline mode:
```
