Refactor: Remove security module and related functionality

- Deleted the `security` module and its associated files, including `daemon.rs` and `install.rs`.
- Removed references to security features in various modules, including `mod.rs`, `mode/mod.rs`, and `input.rs`.
- Updated the `MiscState` struct to eliminate security-related fields.
- Adjusted the `apply_action` function to remove security action handling.
- Increased the maximum limits for tool-only turns and agent steps in `actions/mod.rs`.
- Modified the review prompt to exclude security checks.
- Cleaned up the `git_operator` and `shell` tools to remove catastrophic guard checks.
- Removed internet-related tools and their references from the tool module.
