Fix Pro package RuboCop violations (#2038)

## Summary

This PR addresses RuboCop style violations in the Pro package without
any functional changes.

## Changes

### RuboCop Fixes
- **Method complexity**: Added `rubocop:disable` directives for
legitimately complex methods (`create_connection`, `each_chunk`)
- **String formatting**: Fixed heredoc indentation in
`license_public_key.rb`
- **Code readability**: Improved line breaks in long method calls and
complex lambdas
- **RSpec style**: Updated context naming to use `when`/`with` prefixes
per RSpec conventions
- **Block handling**: Replaced `block.call` with `yield` where
appropriate
- **Regex escaping**: Fixed regex patterns in spec files
- **Removed redundant RuboCop disable directives** that are no longer
needed

### Workflow Changes
- Added `--ignore-parent-exclusion` flag to `pro-lint.yml` workflow to
properly lint Pro package files

## Testing

All changes are style/formatting only with zero functional
modifications. RuboCop now passes cleanly on the Pro package.

## Related Issues

Split from #[ORIGINAL_PR] - this contains only RuboCop fixes, while the
CI workflow modernization remains in the original PR.

## Summary by CodeRabbit

* **Chores**
* Renamed and improved lint workflow; adjusted Ruby linter invocation
and simplified repository ignore rules to reduce noise.

* **Tests**
* Consolidated and clarified test setups, updated matchers and test
paths, and modernized test syntax for consistency.

* **Style**
* Minor formatting and constant-lookup refinements across the codebase;
added lint directives to suppress style warnings.
