Copier update: install CI tooling

[ejfine]

Pull in upstream changes, tested in downstream repo

Summary by CodeRabbit

• Bug Fixes
  • Development environment setup now retries failed network operations, uses safer download checks, and better handles timed-out processes across platforms.
  • Setup verifies that the selected uv executable is available and working, and retries installation of additional development tools.
  • Generated projects now require pytest-recording version 0.14.0 or later.
• Documentation
  • Pull request templates now ask for a test plan, including verification methods, coverage gaps, and checks already handled by CI.

📝 Walkthrough

Walkthrough

The devcontainer installer and its Jinja template add retries, shared download options, and process-tree timeout handling for tool installation commands. The changes also update project metadata, the pytest-recording version requirement, and pull request template guidance.

Changes

Project Template Updates

Layer / File(s)	Summary
Retry and process execution .devcontainer/install-ci-tooling.py, template/.devcontainer/install-ci-tooling.py.jinja	Both installer versions add retry settings, exponential backoff, shared curl options, and process-tree termination for timed-out commands.
Tool installation flows .devcontainer/install-ci-tooling.py, template/.devcontainer/install-ci-tooling.py.jinja	uv, Task, pnpm, Copier, pre-commit, prek, and SSM plugin installation steps use the retry helpers where specified. uv installation verifies the selected executable and its version.
Template and project metadata .config/.copier-answers.yml, .devcontainer/devcontainer.json, extensions/context.py, .github/pull_request_template.md, template/.github/pull_request_template.md	The Copier commit reference, devcontainer context-hash comment, and pytest-recording version requirement change. Both pull request templates add test-plan guidance.
