Space does not toggle items in choose multi-select

[64kramsystem]

Hi!

In Gum 2.0.0, Space does not toggle an item in gum choose --no-limit; x and Tab still work.

To reproduce, run:

printf '%s\n' one two | gum choose --no-limit

Press Space. The highlighted item should toggle, but nothing happens.

The choose keymap registers a literal " ", while KeyPressMsg.String() returns "space" and key.Matches compares the strings exactly. Changing the binding to "space" should fix it.

Environment: macOS, Homebrew, Gum 2.0.0.

Confirmed this is a regression: the official v0.17.0 macOS ARM64 binary toggles the highlighted item with Space.

tab seems to work, FWIW

Confirmed on an internal bash installer using gum choose --no-limit for a multi-select setup picker.

gum 0.16–0.17: Space toggles. gum 2.0.0: Space is a no-op; x and Tab work. Same as @64kramsystem — looks like a regression, and the v2.0.0 note ("While there are no UX changes") does not match.

We had "space toggle" in our picker help text, which misleads 2.x users. Interim fix: version-gated hint (space on 0.x, x on 2.x) until Space is restored or the chosen key is documented for choose --no-limit.

Happy to re-test a fix build.
