Add UI improvements and switching state for branch menu and implement remote-branch-aware checkout logic.
Frontend: add CSS for disabled branch items, compact branch name layout, subtitles and messages; show switching indicator and disable branch actions while switching; display local/remote names and remote subtitles; surface branch switch errors and in-progress messages. Add state.branches.switchingTo and update event handlers to set/clear it.
Backend (tauri): extend LocalRepoBranch with is_remote, remote_name, local_name; add git_ref_exists helper; enhance checkout_branch to detect local vs remote refs and automatically checkout or create tracking branches for remotes; parse refs to include remote branches (skip ones with existing local counterparts) and sort branches with current/local/remote order. Minor formatting tweaks.
Introduce file/application pickers and external-editor integration, plus a visual refresh. Frontend: add UI for selecting/rescanning installed IDEs, custom editor input, "Open in File Explorer" and "Open in Code Editor" actions, clone destination browse, helper utilities, new icons, and many CSS theme/UX improvements (variables, shadows, scrollbars, selection, refined component styles). State: track installedIdes and scan status. Tauri API: expose browseDirectory, browseApplication and scanInstalledIdes, and wire UI handlers to call them. Backend: add InstalledIde struct and update tauri Cargo manifest and capabilities to allow dialogs. Overall improves editor/workflow integrations and modernizes the app styling.
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.
