Research alternative breathing patterns beyond standard in-out

Research alternative breathing patterns

Currently, the application uses the safest and research-based in-out breathing patterns.

Task:

• Investigate other popular or evidence-based breathing patterns aside from the default in-out pattern.
• Compare their suitability, safety, and benefits, especially in the context of breathwork and related CLI applications.
• Document the findings: summarize different patterns, note sources/references, and highlight potential candidates for implementation.

Motivation:
This task is motivated by discussion in PR #5 by @SHJordan about broadening the scope of the breathing patterns supported by the CLI.

• Please include reputable sources and papers if available.
• Consider user safety and accessibility as well as variety and flexibility.
