♻️ refactor: split switch_layout into next_layout and previous_layout…

[EslamMohamed365]

… functions

• Add next_layout() to cycle forward through layouts
• Add previous_layout() to cycle backward through layouts
• Keep switch_layout() as backward-compatible alias to next_layout()
• Update config.conf with example keybinds for both new functions

Pull request overview

Refactors layout switching so users can cycle layouts both forward and backward via separate dispatch functions, while preserving switch_layout() as a compatibility alias.

Changes:

• Introduce next_layout() and previous_layout() backed by a shared internal direction helper.
• Keep switch_layout() as an alias to next_layout() for backward compatibility.
• Extend config parsing and sample config keybinds to support the new functions.

_switch_layout_dir starts with a leading underscore at file scope, which is reserved for the C implementation and can technically invoke undefined behavior / name collisions. Rename this helper to a non-reserved identifier (e.g., switch_layout_dir / switch_layout_dir_internal). Also, the comment says direction < 0 means previous, but the code treats direction == 0 as previous via the else branch—consider handling direction == 0 explicitly (no-op or treat as next) to keep the contract clear.
