Summary

• Preserve ANSI styling in newly captured command output by default, while keeping the SQLite search projection, list preview, and copied text plain.
• Render terminal colors and text attributes in the detail pane and size separators to each pane's current width.
• Persist the installer's selected default search shortcut and clear inherited proxy state in the isolated development installer launch command.

Existing configurations with strip_ansi = true retain their current behavior; users can set it to false to preserve styling in future captures. Previously stripped output remains plain text.

Validation

• cargo test (macOS)
• cargo fmt --check
• cargo clippy --all-targets -- -D warnings
• sh -n scripts/dev-install.sh

The Windows ConPTY runtime test remains part of the CI matrix.
