GitHub app install flow is a dead end for organization repos - the working route (github.com/apps/claude) is never mentioned

When connecting a repository that belongs to an organization, the Claude Code GitHub-app install flow cannot actually complete the install for the org, while the flow itself insists on it:

• The install popup and the settings page contradict each other about the app's install state, so the user cannot tell whether the app is installed or not.
• The install button lands in a place where the organization cannot be reached — the flow only offers targets that don't include the org that owns the repository, so there is no path to finish.
• The route that actually works — going directly to github.com/apps/claude and installing from there, where the organization can be selected — is not mentioned anywhere in the flow.

Expected: the flow either reaches the organization install directly, or points the user at github.com/apps/claude when it can't.

Actual: the flow dead-ends with contradictory state and no mention of the working route; the user has to discover the direct URL on their own.
