Make close-older-issues configurable for scheduled report workflows

[Copilot]

This change makes scheduled report workflows configurable for whether older reports are auto-closed.

Why

Issue #354 requested making close-older-issues configurable instead of always closing older reports.

What changed

• Added a close-older-issues workflow input (default: true) to all scheduled report workflow source definitions (.github/workflows/gh-aw-*.md).
• Kept safe-outputs config in source files on literal booleans so gh-aw compilation remains valid.
• Added scripts/inject-configurable-close.sh to post-process compiled lock workflows and replace hardcoded "close_older_issues":true with $\{\{ inputs.close-older-issues }} where supported.
• Updated Makefile compile target to run the injection script after compilation/backwards-compat processing.
• Regenerated lock workflows to include the new input and runtime-configured close_older_issues value.
• Updated workflow README input tables in gh-agent-workflows/*/README.md to document close-older-issues.

Implementation detail

gh-aw rejects expressions in boolean safe-outputs YAML fields during compile, so this uses a post-compilation substitution in lock files. GitHub Actions evaluates $\{\{ inputs.close-older-issues }} at runtime, producing a valid JSON boolean for the safe-outputs handler.

Usage

jobs:
  run:
    uses: elastic/ai-github-actions/.github/workflows/gh-aw-project-summary.lock.yml@v0
    with:
      close-older-issues: false
    secrets:
      COPILOT_GITHUB_TOKEN: $\{\{ secrets.COPILOT_GITHUB_TOKEN }}

Default remains true, so existing callers keep current behavior.

📝 Walkthrough

Walkthrough

This PR introduces a configurable close-older-issues input across 17 GitHub Actions workflows to enable optional closing of older issues with matching title prefixes. Each workflow gains a new boolean input (default: true), expanded outputs for sanitized text computation, and dynamic reference injection via a new helper script.

Possibly related PRs

• Prefix internal workflows with Internal: #348: Updates the same workflow name field in .github/workflows/agentics-maintenance.yml, directly modifying the same target that was previously changed in PR #348.
• Replace backwards compat symlinks with copies #341: Both PRs introduce post-build script invocations in the Makefile compile target (inject-configurable-close.sh vs backwards-compat.sh), representing similar repository maintenance patterns.

Poem

🐰 Close-older-issues now sings with choice,
No more hardcoded strings rejoice!
From true to input, dynamic and free,
Workflows configurable, as they should be!
Scripts inject the logic we seek,
One toggle to rule them, so sleek. ✨
