feat: add scripts for merging pull requests by title and from a list, and validate PR titles

[joshjohanning]

New batch PR merge and validation tooling:

• Added merge-pull-requests-by-title.sh, a script that finds and merges open pull requests matching a title pattern (supports wildcards) across repositories listed in an input file, with options for merge method, custom commit title, and dry-run mode.
• Added merge-pull-requests-from-list.sh, a script to merge PRs from a file of PR URLs, supporting merge method selection, custom commit title/body (with template variables), and dry-run preview. Skips closed or already merged PRs.
• Added validate-pr-titles.sh, a script to check that all PRs in a list have the same title, reporting the majority title and listing outliers for consistency checks before batch merges.

Documentation updates:

• Updated gh-cli/README.md to add usage instructions, input formats, and examples for the new scripts, making it easier for users to understand and adopt these automation tools. [1] [2]
