Instead of requiring org installation IDs to be statically configured in
cachew.hcl, dynamically resolve them by querying the GitHub API
(GET /orgs/{org}/installation, falling back to /users/{user}/installation).
Removes the static Installations map from Config entirely. Installation
IDs are discovered on first use and cached in memory. The fallback-org
config is retained for orgs where the app is not installed.
This fixes clone failures for orgs like AfterpayTouch where the GitHub
App is installed but the installation ID wasn't in the config. Ports the
same approach used in blox's internal/github/app_auth.go.

Instead of requiring all org installation IDs to be statically configured in
cachew.hcl, dynamically resolve them by querying the GitHub API (GET /orgs/{org}/installation, falling back to/users/{user}/installation).Static installations config still works and is checked first. Dynamic discovery only triggers for orgs not in the static map. Results are cached in memory for subsequent requests.
This fixes clone failures for orgs like
AfterpayTouchwhere the GitHub App is installed but the installation ID wasn't in the config. Ports the same approach used in blox'sinternal/github/app_auth.go.
