[Bug] r8-analyzer

### Affected Skill

`performance/r8-analyzer`

### Description

The `r8-analyzer` skill requires two Python scripts during the AGP 9.3+ analysis workflow:

- `scripts/convert_pb_to_json.py`
- `scripts/analyze.py`

However, the published skill contains only `SKILL.md` and the `references/` directory. The `scripts/` directory is missing.

As a result, an agent cannot complete the mandatory Path A workflow or produce the required `tmp/keepradius/analysis_result.txt` report.

The issue is reproducible both from the current repository contents and from a clean installation using Android CLI.

### Expected Behavior

After installing `r8-analyzer`, every file referenced by its mandatory workflow should be included.

The following commands should resolve to existing scripts and run successfully:

```bash
python3 .agents/skills/r8-analyzer/scripts/convert_pb_to_json.py
python3 .agents/skills/r8-analyzer/scripts/analyze.py

Start by inspecting the performance/r8-analyzer skill package and SKILL.md references, then reproduce the clean-install failure with the two Python commands in the issue. Confirm that scripts/convert_pb_to_json.py and scripts/analyze.py are included in the published skill, both commands run successfully, and tmp/keepradius/analysis_result.txt can be produced.
