chore(release): bump to v2.4.0 (#37)

Release prep for **2.4.0**.

## Changes
- `package.json`: `2.3.0` → `2.4.0` (minor — new `init` command).
- `CHANGELOG.md`: `[Unreleased]` → `[2.4.0] - 2026-06-01`, fresh empty
`[Unreleased]`, compare links updated.

## What ships in 2.4.0
- `init` command — agent adoption layer (#34)
- Opt-in agent selection + interactive picker (#36)

## After merge
Dispatch the **Publish** workflow (workflow_dispatch on main) → tags
`v2.4.0`, `npm publish --tag latest` via OIDC, creates the GitHub
Release.
