feat(cli): integrate jmespath-extensions for enhanced query capabilities

Add 150+ extended JMESPath functions for more powerful query and
transformation capabilities when using the -q/--query flag.

New function categories:
- String: upper(), lower(), trim(), split(), replace()
- Type: type_of(), is_empty(), to_number(), to_string(), default()
- Math: round(), min(), max()
- Utility: if(), coalesce(), unique()
- DateTime: now(), format_date()
- Validation: is_ipv4(), is_ipv6(), is_email(), is_url()
- Encoding: base64_encode(), base64_decode()

Changes:
- Add jmespath_extensions dependency with selective features
- Update output.rs to use extended runtime with OnceLock
- Add compile_jmespath() helper for consistent usage
- Update cloud/utils.rs and enterprise/utils.rs to use extended runtime
- Add comprehensive tests for extension functions
- Update documentation with examples of new functions

Closes #481
