[Tech] update skill to reference coinfello cli

[BrettCleary]

This pull request updates the CoinFello CLI documentation and codebase to fully transition from the old openclaw CLI to the new @coinfello/agent-cli package. It also removes the deprecated redelegation flow, improves delegation uniqueness, and updates tests and scripts for better reliability and clarity.

CLI and Documentation Updates:

• All documentation, usage examples, and error messages have been updated to reference npx @coinfello/agent-cli instead of the deprecated openclaw CLI. This change is reflected across SKILL.md, REFERENCE.md, and all code comments and scripts. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]

Feature and Code Changes:

• The redelegation flow (--use-redelegation option) has been removed from the CLI and documentation, simplifying the delegation process to always create a fresh subdelegation per prompt. [1] [2] [3] [4] [5] [6] [7] [8]
• Subdelegations now use a unique random salt for each delegation, improving security and preventing replay issues. [1] [2]

Testing and Reliability Improvements:

• Increased test and CLI script timeouts to 6 minutes to reduce flakiness in end-to-end tests and long-running operations. [1] [2]
• Enhanced end-to-end tests to better simulate repeated prompt flows and verify correct delegation handling. [1] [2]

Other Updates:

• Bumped the package version to 0.1.1 to reflect these changes.

These updates make the CLI easier to use, more secure, and better aligned with current best practices.
