feat: display opencli version dynamically from CI build

[ByteYue]

Description

Currently the website hardcodes v1.0 in the hero badge, while opencli is already at v1.2.6.

This PR:

1. Reorders the deploy workflow to checkout opencli repo before building the website
2. Extracts the version from opencli's package.json and injects it as VITE_OPENCLI_VERSION env var during Vite build
3. Updates App.tsx to read the env var dynamically (with v1.0 fallback for local dev)
4. Adds version-released to the repository_dispatch event types

Companion PR: ByteYue/opencli#2 — ci: trigger website rebuild on release

Changes

• deploy.yml: Reorder steps, extract version, inject VITE_OPENCLI_VERSION
• App.tsx: Replace hardcoded v1.0 with import.meta.env.VITE_OPENCLI_VERSION || '1.0'
