Antigravity 2.0.x Unable to Reference Android CLI Skills

### Affected Skill

All Android CLI Skills

### Description

After updating to Antigravity 2.0.x, I am no longer able to reference Android CLI skills in prompts, even after running `android skills add --all` or `android init`.

This was working correctly in previous versions.

### Expected Behavior

After running `android skills add --all` or `android init`, the installed Android CLI skills should be available and referenceable within Antigravity prompts.

### Actual Behavior

Even after successfully running `android init` and `android skills add --all`, none of the Android CLI skills can be referenced or detected in Antigravity 2.0.x prompts.

### Steps to Reproduce

1. Install or update Antigravity to version 2.0.x (tested on 2.0.3).
2. Install Android CLI (if not already installed).
3. Run:

```bash
android init
```

or

```bash
android skills add --all
```
4. Try referencing any Android CLI skill in an Antigravity prompt.
5. Observe that the skills are not recognized or available.

### Suggested Fix

Possibly related to a regression in skill registration, indexing, or prompt integration introduced in Antigravity 2.0.x.

Start by reproducing the issue with Antigravity 2.0.3 using `android init` and `android skills add --all`, then trace the Android CLI skill registration, indexing, and prompt integration entry points. Done means installed Android CLI skills are detected and referenceable in Antigravity prompts after either command.
