fix: fix bun install bug (#62)

* fix: fix bun install bug

- Add assertExecutable() to cli-shared that checks and attempts chmod
- Simplify CLI and SDK spawn code to use the shared helper
- Fix cli-shared package.json exports (.js not .mjs)
- Add global install instructions to SDK error message

* chore(release): update version to 0.1.6-rc.1

* fix: add cli-shared package to Dockerfiles

* chore(release): update version to 0.1.6-rc.1

* fix: add cli-shared publishing to release workflow

* chore(release): update version to 0.1.6-rc.1

* fix: handle already-exists error during crate publish

* chore(release): update version to 0.1.6-rc.1
