Zed: extension publish action fails with 'no replacements occurred'

[avifenesh]

The v0.14.0 release workflow failed to publish the Zed extension.

Error: `Error: no replacements ocurred`

The `huacnlee/zed-extension-action@v2` could not find the agnix entry in the Zed extensions registry `extensions.toml` to update the version. This may be because:

• The extension name format doesn't match what the action expects
• The extension hasn't been added to the Zed extensions registry yet
• The action's regex pattern doesn't match the entry format

Workflow step: `.github/workflows/release.yml` - "Publish Zed Extension"

Needs investigation into how the Zed extensions registry format works and whether agnix is properly registered.

Root cause identified: The huacnlee/zed-extension-action@v2 uses a regex that only handles ONE line between the [extension] header and the version field. The agnix entry has TWO intermediate lines (submodule and path), breaking the match.

Workaround: Manually submitted version update PR to the Zed extensions registry: zed-industries/extensions#5020

Fix for future releases: Either:

1. Submit a PR to huacnlee/zed-extension-action to fix the regex (make (.*\s*) handle multiple lines)
2. Replace the action with a manual step that does the extensions.toml update via API

Going with option 2 in the release workflow since it's more reliable.
