Related Issue

Resolve #1022

Problem

See linked issue.

What changed

• Added a terminal.show_hardware_cursor TUI preference and /settings selector for hardware cursor visibility.
• Applied the setting during startup and /reload / /reload-tui so IME candidate windows can follow the input cursor on terminals that require a visible hardware cursor.
• Updated the default tui.toml render path, migration stub detection, tests, docs, and changeset.

Note: Local verification used --config.engine-strict=false because this Windows environment has Node v22.19.0, below the repo requirement >=24.15.0.
