publish MCP-inspector cross-platform and add brew support

[davidawad]

it would be much nicer to do a brew install than npx run.

I know it's a nitpick but hopefully shouldn't be too painful to add this.

@davidawad sounds interesting will check the possibilities

I haven't looked at all the details yet, but I think we'd want to see whether this project qualifies to be on Homebrew Core: https://docs.brew.sh/Acceptable-Formulae

Closing as not planned and labeling with v2 in case we want to review for next version.
