[Bug]: Openwiki --update keeps changing the Bitbucket Pipelines to GitHub Actions in a Bitbucket project

Description

In the AGENTS.md The update process keeps inserting

<!-- OPENWIKI:START -->

## OpenWiki
.
.
.
The scheduled OpenWiki GitHub Actions workflow refreshes the repository wiki. Do not hand-edit generated OpenWiki pages unless explicitly asked; prefer updating source code/docs and letting OpenWiki regenerate.

<!-- OPENWIKI:END -->

I believe this part is static, but it doesn't make any sense to reference GitHub Actions is a bitbucket project, that even has a bitbucket-pipelines.yml file in it.

Steps to Reproduce

1. A bitbucket git project, that has bitbucket-pipelines.yml in its root directory and an AGENTS.md file.
2. Run openwiki --init
3. in AGENTS.md, change GitHub Actions to Bitbucket Pipelines manually.
4. Run openwiki --update

Expected Behavior

It shouldn't change Bitbucket Pipelines to GitHub Actions.

Actual Behavior

It changes Bitbucket Pipelines to GitHub Actions.

Environment

• OS: Windows or Linux
• Node.js version: 22 or 24
• OpenWiki version: 0.5.0, also older versions had the same issue.
