Implement local repository scanning end-to-end. Frontend: add UI (toolbar, local-scan panel, list/cards), CSS styles, icons, new state fields, and templates; convert recent repo items to buttons and wire up actions to select, view and open scanned repos. JS: add helper utilities (repoNameFromPath, normalizeRemoteUrl, serverRepoRemoteUrls), scanForLocalRepos/selectLocalRepo functions, render template for scan results, and call scanLocalRepos via tauri-api. Tauri API: expose scan_local_repos (tauri command) in tauri-api.js. Backend (Rust): add LocalRepoCandidate type and a scanner implementation that walks configurable/default roots, deduplicates paths, matches local remotes against allowed server URLs, enforces depth/result limits, and returns matched candidates; register scan_local_repos in the command list. Includes error handling and user-facing messages for missing roots or remotes.
Implements a read-only repository viewer for remote Gitea repos and local clones. Adds UI/CSS for viewer panels, breadcrumb/branch controls, file table, code/Markdown preview, and readme rendering (frontend/css/components.css, frontend/js/app.js). Extends app state and wiring (state.js, app.js) with viewer actions, branch/content loading, local/remote navigation, and preview helpers (base64 decoding, markdown rendering, syntax highlighting, 256 KB preview limit). Adds Gitea API helpers to fetch repo branches and contents (frontend/js/gitea-api.js) and Tauri JS bindings for local repo operations (tauri-api.js). Implements Rust backend commands to list branches, tree entries, and file contents (with size/binary checks and helper utilities) and wires them into the Tauri command registry (src-tauri/src/lib.rs). Also updates README to mention the new read-only viewer.
