Pull request overview

This PR consolidates GitHub Actions lint workflows by removing superseded squad-standard-lint-* definitions and relying on the existing squad-lint-* workflows to keep markdown/YAML linting consistent and non-duplicative.

Changes:

• Deleted the superseded squad-standard-lint-markdown.yml and squad-standard-lint-yaml.yml workflows to eliminate duplication.
• Updated squad-lint-markdown.yml and squad-lint-yaml.yml workflow triggers (and markdownlint globs) as part of the consolidation.

.github/workflows/squad-lint-yaml.yml:6

• The push trigger was changed from dev/insider to dev/release. This drops YAML lint coverage on the insider branch and (combined with the pull_request change below) may also reduce coverage on main, contradicting the PR/issue goal of keeping lint coverage intact. If release is intended, consider adding it rather than replacing existing branches.
  .github/workflows/squad-lint-yaml.yml:9
• The PR trigger was narrowed to dev/release, which means YAML lint will no longer run for PRs targeting main (and previously preview/insider). This appears to conflict with the stated intent to keep CI lint coverage intact when removing the superseded workflows.
  .github/workflows/squad-lint-markdown.yml:6
• The push trigger was changed from dev/insider to dev/release. This drops markdown lint coverage on the insider branch and may be unintended given the issue scope focused on consolidating filenames while keeping coverage.
  .github/workflows/squad-lint-markdown.yml:8
• The PR trigger was narrowed to dev/release, which stops markdown lint from running on PRs targeting main (and previously preview/insider). This seems at odds with the PR description’s claim that lint coverage is kept intact after removing the old workflows.
