RespawnRequest configures restarting a window's or pane's process on tmux 3.2a or later. Its zero value reuses the stored command and directory and requires the target process to be inactive. Nil pointer fields omit their options; nonnil pointers are explicit, including empty strings. There are no mutually exclusive fields. Arguments and environment entries are validated before execution.

Methods read pointer and map values during argument construction; do not
mutate them concurrently.

## Members

- `Command` (attribute) — Command is omitted when nil so tmux reuses the stored command. A nonnil empty string remains an explicit operand.
- `StartDirectory` (attribute) — StartDirectory expands ~ and ~/... for the current user. Nil reuses the stored directory; a nonnil empty string selects the current directory.
- `Environment` (attribute) — Environment is emitted in lexically sorted key order; nil and an empty map both add no environment entries.
- `Kill` (attribute) — Kill terminates an active target process before restarting it.
