Refactor ShellSpec test infrastructure and generation system
Restructure test directory with version 1 archive of prior work and a
new modular architecture under test/runners.
Test generation:

Add Ruby-based ShellSpec test generator with YAML schema support
Modularize placeholder substitution and use when_command in schema
Make shellspec_name the single source of truth (extracted from YAML)
Add YAML validation script (validate_yaml.rb)
Handle command timeouts, failures, and empty output gracefully
Fix env var substitution to match longest token first
Escape backticks in output to prevent shell evaluation
Force UTF-8 encoding on output handling during SysExec calls
Exit matcher generation on awk errors

Test coverage:

Add generated tests for divergent tree, zelta revert, and zelta clone
Break divergent tree setup into discrete phases (initial, backup, divergence)
Wrap divergent tree tests with Describe blocks for conditional Skip If

Environment and portability:

Add helpers to configure env vars from the last tmp-installed zelta
Allow bypass of process-based env vars for pre-configured environments
Use which instead of command -v for Ubuntu compatibility
Use ls -1d for portable directory listing
Use sudo for local zfs allow; update error checks after permission changes

Project structure:

Reorganize test/runners into env/ and test_generation/ directories
Implement absolute path resolution (SCRIPT_DIR pattern) across all scripts
Rename manual_cleanup.sh to test_generator_cleanup.sh
Move .rubocop.yml to lib/ruby/, fix RuboCop warnings

Documentation:

Rewrite test_generation and test/runners READMEs
Add debugging workflow docs and file hierarchy restructuring plan
