fix(examples): patch vulnerable npm dependencies (#1347)

## What
- bump `examples/browser` to `vite@^6.4.2`
- pin `langsmith` to `0.5.20` in example JS workspaces
- refresh the affected package-lock files only

## Why
- clears the open Dependabot alerts in the example/browser and JS
package lockfiles without changing runtime code paths

## How
- use npm overrides for transitive `langsmith`
- move the browser example to a non-vulnerable `vite` release on the
same major line
- regenerate lockfiles with `npm install --package-lock-only
--ignore-scripts`

## Verification
- `npm audit --json` in `examples/browser`
- `npm audit --json` in `examples`
- `npm audit --json` in `crates/bashkit-js`
- `TMPDIR=$PWD/.tmp-test just pre-pr`
