[explorer] add local explorer hotkey to the vite plugin

[emily-shen]

this uses e like in wrangler, which doesn't conflict with any default vite hotkeys.

vite doesn't have a way of hiding bindings, so this should not be merged until we are ready to properly announce this.

Also, we seem to use open in c3 and wrangler to open browsers, so i've used it here too in the vite plugin, and added it to the pnpm catalog and updated the version from 8 -> 11. open v11 is ESM only, but it seems fine? I vaguely remember we have tried to move off as many CJS packages as possible, not sure if this was skipped on purpose.

[ask-bonk]

I've now thoroughly reviewed all the changes. Let me summarize my findings:

The implementation is clean and follows existing patterns well. The code:

1. Correctly mirrors wrangler's e hotkey implementation from packages/wrangler/src/dev/hotkeys.ts
2. Uses CorePaths.EXPLORER constant properly
3. Has proper TTY guard matching the bindings shortcut pattern
4. Handles resolvedUrls being undefined gracefully
5. Properly handles the open() error case (matching wrangler's pattern, but with a more helpful error message that includes the URL)
6. The open dependency is correctly placed in devDependencies since tsdown bundles it
7. The catalog entry for open is properly added to pnpm-workspace.yaml and existing open deps in create-cloudflare and wrangler are migrated to use it
8. Tests are well-structured
9. The changeset is properly formatted

The only thing I notice is not really an issue but worth noting: in wrangler, the explorer hotkey has its label intentionally hidden (commented out) to keep it secret before announcement, while the vite plugin has a visible description: "open local explorer". But the PR description explicitly notes "this should not be merged until we are ready to properly announce this," so this is intentional.

LGTM
