FEATURE: GitHub org search and view basic detail

### Feature and its Use Cases

Feature
-Landing page where users search for a GitHub organization by name.
-Search behavior: uses the GitHub Search API for organizations; if search returns nothing, falls back to fetching an org by exact login (GET /orgs/:login).
-Multiple matches: show a list; user picks one to open the profile.
-Single match: navigate straight to the organization detail route.
-Organization detail page showing basic public profile data (name, description, location, blog, social link if present, public repos, followers, created date, link to GitHub).
