- automated_updates_data.json: tracks last processed commit and past improvements
- scripts/update-docs-from-commits.js: analyses recent GDevelop commits and
  invokes Claude Code (or Codex) to update docs accordingly
- scripts/improve-docs.js: picks a new documentation area to improve each run,
  tracks what was improved so future runs don't repeat
- scripts/package.json: minimal package manifest for the scripts folder

- Add 'pull_request' to 'on:' in both workflows so they run on PRs
- Set 'base: main' in peter-evans/create-pull-request to fix the
  'base input must be supplied' error on detached-HEAD checkouts
- Capture and print AI agent stdout so output is visible in CI logs

- automated_updates_data.json: format empty array with newline for
  cleaner diffs when entries are added
- improve-docs.js: AI now edits automated_updates_data.json directly
  (adds to last_improved_things) instead of writing improvement_summary.txt;
  script reads back the new entry and writes summary to /tmp/ai_summary.txt
- update-docs-from-commits.js: prompt now asks for a brief summary;
  script writes AI output to /tmp/ai_summary.txt and commit log to
  /tmp/commit_log.txt; uses writeDataFile helper for consistent formatting
- improve-docs.yml: reads AI summary as step output and includes it in
  the PR body ('The AI agent summary is:')
- update-docs-from-commits.yml: reads AI summary + commit log as step
  outputs and includes both in the PR body
- .gitignore: remove unused improvement_summary.txt entry

Replaces fixed SUMMARY_EOF/COMMITS_EOF delimiters with randomized ones
(EOF_<random hex>) and adds an extra blank line before the closing
delimiter to ensure GitHub parses the multiline output correctly.
