Add continuous documentation workflow automation

[Copilot]

Implements four GitHub Actions workflows to prevent documentation drift through automated maintenance.

Workflows

Daily Documentation Updater (daily-doc-updater.yml)

• Runs: Daily at 00:00 UTC
• Reviews docs for accuracy, broken links, outdated references
• Creates PRs when updates needed

Glossary Maintainer (glossary-maintainer.yml)

• Trigger: Push to main with .md changes
• Syncs AI_Glossary.md with terminology used in documentation
• Adds missing terms, maintains alphabetical order

Documentation Unbloat (doc-unbloat.yml)

• Runs: Weekly Sunday 00:00 UTC
• Reduces verbosity, simplifies complex sentences
• Targets ~15-20% word count reduction where applicable

Documentation Noob Tester (doc-noob-tester.yml)

• Runs: Monthly on 1st at 00:00 UTC
• Simulates beginner learning path
• Creates issues (max 3-5) for genuine pain points

Structure

Each workflow comprises:

• .yml - GitHub Actions configuration using github/gh-aw@v0.42.13
• .md - Agent instructions with objectives, tasks, and guidelines

Follows existing pattern from issue-triage-agent.yml. All workflows support manual triggering via workflow_dispatch.

Documentation

Added .github/workflows/README.md documenting all workflows, schedules, and expected behavior.

<issue_title>Proposal: Add "Continuous Documentation" Agentic Workflow</issue_title>
<issue_description>### Feature Request

I propose implementing Continuous Documentation Workflows to automate the maintenance of this repository's documentation.

Proposed Workflows

I suggest adding the following agentic automations to github/workflows/:

• Daily Documentation Updater (96% merge rate): Reviews and updates documentation to ensure accuracy.
• Glossary Maintainer (100% merge rate): Keeps the glossary synchronized with codebase changes.
• Documentation Unbloat (85% merge rate): Reviews and simplifies documentation by reducing verbosity.
• Documentation Noob Tester: Simulates a new user journey to identify confusing steps.

Impact

These workflows challenge conventional wisdom about AI-generated technical content. While human review remains essential, these agents provide a dramatically better baseline than the alternative (no docs at all), effectively solving documentation drift.
