Island: Sandboxing tool powered by Landlock

Hi,

I just released Island, a sandboxing tool powered by Landlock:
https://github.com/landlock-lsm/island

Island makes Landlock practical for everyday workflows by acting as a
high-level wrapper and policy manager.  Developed alongside the kernel
feature and its Rust libraries, it bridges the gap between raw security
mechanisms and user activity through:
- Zero-code integration: Runs existing binaries without modification.
- Declarative policies: Uses TOML profiles instead of code-based rules.
- Context-aware activation: Automatically applies security profiles
  based on your current working directory.
- Full environment isolation: Manages isolated workspaces (XDG
  directories, TMPDIR) in addition to access control.
- Transparent shell integration: Automatically sandboxes commands in
  your shell without changing your workflow.
- Zero-privilege operation: No root access or special capabilities
  required.
- Layered protection: Multiple profiles compose cleanly with
  deterministic ordering.

It's a work in progress, so be careful.

Feedback welcome!

Regards,
 Mickaël
