Fix CI to always run full test suite on master branch (#2035)

## Summary

Fixes critical CI logic flaw where documentation-only commits on master
would skip all tests, allowing broken states to persist undetected.

## Problem

The `paths-ignore` directive was being applied to BOTH pull requests AND
master branch pushes, causing:

1. **Doc-only commits on master skip ALL CI tests** - If commit A has
failing tests, then commit B (doc-only) merges to master, the broken
state persists with no CI feedback
2. **Inconsistent test coverage** - Master should always run the full
test suite (both latest AND minimum dependency versions)
3. **Silent failures** - Test failures can be hidden by subsequent
documentation commits

## Solution

Remove `paths-ignore` from push events on master branch while keeping it
for pull requests:

```yaml
on:
  push:
    branches:
      - 'master'
    # Never skip on master - always run full test suite
  pull_request:
    paths-ignore:
      - '**.md'
      - 'docs/**'
```

This ensures:
- ✅ Master ALWAYS runs complete test suite (both latest AND minimum
deps)
- ✅ PRs can still skip irrelevant tests for faster feedback
- ✅ No more silent failures hidden by doc-only commits

## Files Changed

All main CI workflows updated:
- `integration-tests.yml`
- `gem-tests.yml`
- `lint-js-and-ruby.yml`
- `package-js-tests.yml`
- `pro-integration-tests.yml`
- `pro-lint.yml`
- `pro-test-package-and-gem.yml`
- `examples.yml`
- `playwright.yml`

## Test Plan

- Verified workflow syntax with `actionlint`
- Confirmed linting passes locally
- CI will validate on this PR

## Summary by CodeRabbit

## Chores
* Ensured master branch pushes always run the full CI/test suite by
removing path-based skip rules that previously excluded docs and other
file types; pull request trigger behavior remains unchanged.
