This improves local agent workflows and SSH/SFTP navigation while fixing terminal input and rendering issues. Agent launches now share a project-and-shell picker, Codex has its own sidebar view, and clicking an SSH prompt directory opens the terminal's companion SFTP pane at that location.

Changes

• Add a dedicated Codex view with session navigation, attention states, messages and resource monitoring through the existing agent infrastructure. Codex completion notifications use its notify hook; ongoing activity uses terminal/process monitoring.
• Add normal and custom agent launch cards with shell selection, Tab-completed project directories, saved shortcuts and bounded recent-folder history. Custom commands retain their flags and use the selected shell's normal profiles, functions and aliases.
• Fix Shift+Enter multiline input in integrated shells and remove stale command decorations after clear/cls. Keep tab expansion stable near the close button.
• Show image controls only for detected Claude/Codex sessions. Support PNG/JPEG selection, clipboard and drop input with colored attachment labels and image-only hover previews; prevent duplicate first-image insertion and repeated-layout paste/drop handling.
• Share terminal color capability hints between PTYs and SSH sessions, remove inherited NO_COLOR from local terminal children, and retain ANSI, indexed and RGB rendering through the existing renderer. Improve button contrast and add the attributed Codex logo.
• Open or reuse SFTP beside the source SSH terminal, using the same companion pane as Ctrl+Shift+F. Recognize paths embedded in prompts and preserve the prompt account when resolving tilde paths: after root runs su prisma, prisma's ~/project resolves against prisma's actual server home rather than /root. The remote editor shares this path resolver.
• Add versioned machine-setup import/export with review and duplicate filtering. Export names, endpoints, usernames and colors while excluding keys, key paths, passwords and passphrases.
• Add bounded background SSH-key and Bitvise-profile discovery with selectable full-path results, and refine the import/export dialogs.

Validation

• cargo fmt --all --check
• cargo clippy --all-targets --target x86_64-pc-windows-gnullvm -- -D warnings
• cargo test --all-targets --target x86_64-pc-windows-gnullvm: 383 unit tests passed, plus local PTY, shell-integration and headless UI flows.
• Added a self-contained loopback SSH/SFTP regression that authenticates as root, resolves a prisma prompt with a custom home containing spaces, and verifies SFTP navigation to the clicked directory and a subsequent destination. Included this test in CI.
• Windows portable build startup smoke test passed.
• Fork Windows CI passed for 3fe4e6d, including formatting, Clippy, unit tests and the loopback SSH/SFTP regression.

The branch is based on the current upstream main (1bf3fb3). Baseline rustfmt/Clippy compatibility adjustments are isolated in the first commit.
