Extension not indexed by gallery crawler despite meeting all listing requirements (citlyze-mcp)

### URL of the page with the issue

https://geminicli.com/extensions/

### What is the problem?

Our extension meets all documented gallery listing requirements but has not been indexed by the crawler after 72+ hours.

Extension repository: https://github.com/citlyze/citlyze-mcp

Verification of each documented requirement (per the releasing docs):
1. Public GitHub repository: yes
2. gemini-extension.json at the absolute root: yes
3. gemini-cli-extension topic on the repo: yes, added 2026-08-15, and the repo is returned by the GitHub search query `topic:gemini-cli-extension org:Citlyze`
4. Tagged repository: yes, tag v1.0.0
5. Local validation passes: `gemini extensions validate .` reports the extension has been successfully validated (latest CLI via npx)

The extension does not appear in gallery search or in geminicli.com/extensions.json (checked 2026-08-19; 1498 entries, none matching). Installation works fine via `gemini extensions install https://github.com/citlyze/citlyze-mcp`, so this looks like a crawler/indexing issue rather than a manifest problem. Symptoms appear identical to #28208.

Happy to provide any additional details.

### What did you expect to happen?

The extension should be discovered by the daily crawler and appear in the gallery at geminicli.com/extensions (and in extensions.json), like other public tagged repositories carrying the gemini-cli-extension topic.

### Additional context

_No response_

Start with geminicli.com/extensions and extensions.json, then trace the crawler handling GitHub repositories returned by topic:gemini-cli-extension and compare the symptoms with issue #28208. Validate the cited repository with `gemini extensions validate .`; done means the tagged extension is included in the gallery search and extensions.json.
