draft: @game-ci/itch-deploy plugin (structural skeleton)

[frostebite]

Structural skeleton for an itch.io deploy plugin (game-ci deploy itch), mirroring @game-ci/steam-deploy's shape exactly (engine-agnostic, dispatched via the deploy command's '*' engine wildcard). Not functional yet - execute() throws, pointing to the README. Should be one of the faster ones to bring to real functionality, since itch.io's butler CLI is straightforward.

See plugins/itch-deploy/README.md for what's real vs. TODO.

Superseded by #142, which lands this skeleton verbatim.

Consolidated rather than merged individually: every one of these PRs touches bun.lock (each adds its own plugins/* workspace member), so merging #124 immediately conflicted all 14 remaining PRs. Merging them one at a time would have meant 14 more rounds of regenerate-lockfile → push → re-run CI, each invalidating the next. #142 regenerates the lockfile once and passes bun install --frozen-lockfile.
