[Feature] Remote Explorer: Browse and open remote server directories over SSH

[princejain756]

Problem / 问题

Currently in v0.15.3, while remote servers can be paired via SSH under Settings → Remote Hosts, there is no Remote Explorer or remote directory browser in the main UI (Create Project / Open Workspace). Users working on remote headless servers (cloud VMs, devboxes) cannot browse remote filesystem paths or select a remote folder to work on.

Proposed change / 期望改动

1. Add a "Remote Explorer" view / panel (similar to VS Code Remote - SSH) showing paired SSH hosts and their directory trees.
2. In the "Create Project / Open Workspace" dialog, add a "Remote Host" source option allowing users to browse and pick a remote Linux path via workspace/list.
3. Allow the agent sessions, terminals, and file tree explorer to operate directly on the remote server workspace.

Alternatives / 其他方案

Using local checkouts or mounting servers via SSHFS/FUSE, which adds overhead and lacks agent execution context on the server.

Additional context / 补充信息

Relates to #176 and #140.
