ci: apply E2E CI optimizations to Claude workflows (#12097)

## Summary

Applies the CI performance optimizations from #12090 to Claude Code
workflows.

## Changes

### `claude.yml` & `claude-dependabot.yml`
- **pnpm caching**: Replaced manual `actions/cache` with `setup-node`
built-in `cache: "pnpm"`
- Removes 4 steps (set pnpm store dir, cache step, manual config) → 1
step

### `claude-ci-failure-auto-fix.yml`
- **Added dev environment setup** with optimized caching
- Now Claude can run lint/tests when fixing CI failures (previously
could only edit files)
- Uses the same optimized caching patterns

## Dependency

This PR is based on #12090 and will merge after it.

## Testing

- Workflow YAML syntax validated
- Patterns match proven #12090 implementation
- CI caching changes fail gracefully to uncached builds

## Linear

Fixes [SECRT-1950](https://linear.app/autogpt/issue/SECRT-1950)

## Future Enhancements

E2E test data caching could be added to Claude workflows if needed for
running integration tests. Currently Claude workflows set up a dev
environment but don't run E2E tests by default.

<h2>Greptile Overview</h2>

<details><summary><h3>Greptile Summary</h3></summary>

Applies proven CI performance optimizations to Claude workflows by
simplifying pnpm caching and adding dev environment setup to the
auto-fix workflow.

**Key changes:**
- Replaced manual pnpm cache configuration (4 steps) with built-in
`setup-node` `cache: "pnpm"` support in `claude.yml` and
`claude-dependabot.yml`
- Added complete dev environment setup (Python/Poetry + Node.js/pnpm) to
`claude-ci-failure-auto-fix.yml` so Claude can run linting and tests
when fixing CI failures
- Correctly orders `corepack enable` before `setup-node` to ensure pnpm
is available for caching

The changes mirror the optimizations from PR #12090 and maintain
consistency across all Claude workflows.
</details>


<details><summary><h3>Confidence Score: 5/5</h3></summary>

- This PR is safe to merge with minimal risk
- The changes are CI infrastructure optimizations that mirror proven
patterns from PR #12090. The pnpm caching simplification reduces
complexity without changing functionality (caching failures gracefully
fall back to uncached builds). The dev environment setup in the auto-fix
workflow is additive and enables Claude to run linting/tests. All YAML
syntax is correct and the step ordering follows best practices.
- No files require special attention
