Move Lazer documentation to Pro section and remove lazer folder

[devin-ai-integration]

Description

This PR migrates the detailed Pyth Lazer technical documentation to the Pyth Pro section, completing the product rebrand. The placeholder content at /price-feeds/pro/how-lazer-works has been replaced with the comprehensive technical documentation that was previously located in the /lazer folder.

Changes made:

• Replaced placeholder content in /pages/price-feeds/pro/how-lazer-works.mdx with detailed technical documentation covering the 5-tier architecture (Publishers, Relayers, Message Queue, Routers, History Service)
• Updated all product name references from "Pyth Lazer" to "Pyth Pro" throughout the content
• Removed the legacy /pages/lazer/ folder after content migration
• Existing redirects in next.config.js will continue to handle legacy /lazer/* URLs

Type of Change

• New Page
• Page update/improvement
• Fix typo/grammar
• Restructure/reorganize content
• Update links/references
• Other (please describe):

Areas Affected

• /pages/price-feeds/pro/how-lazer-works.mdx - Content replaced with full technical documentation

Additional Notes

Important for reviewers:

1. Test redirect functionality: Verify that /lazer/how-lazer-works properly redirects to /price-feeds/pro/how-lazer-works (redirects defined in next.config.js lines 127-128)
2. Verify rebrand accuracy: Spot-check that "Lazer" → "Pro" replacements make sense in context, particularly in the technical descriptions
3. Check navigation: Confirm the page appears correctly in the Pro section sidebar and that the legacy folder removal doesn't break any navigation elements
4. Test internal links: Other pages reference /lazer paths - verify these are properly redirected (examples found in subscribe-price-updates.mdx and integration guides)

Redirect coverage: This PR relies on existing redirects in next.config.js. The following redirect rules should handle legacy URLs:

["/lazer", "/price-feeds/pro"],
["/lazer/:path*", "/price-feeds/pro/:path*"],

Vercel Deployment Status

I've investigated the failing "Vercel – documentation" check and wanted to provide context:

What I've verified:

• ✅ Local build passes: npm run build completes successfully with no errors
• ✅ All GitHub Actions checks pass: pre-commit, test
• ✅ Primary Vercel deployment succeeds: "Vercel – docs" (pyth-network/docs) deployed successfully with working preview at https://docs-git-devin-1761672971-move-lazer-docs-to-pro-pyth-network.vercel.app
• ❌ Secondary Vercel deployment fails: "Vercel – documentation" (pyth-stuff/documentation)

Analysis:
Since the code builds locally and the primary "docs" deployment succeeded, this appears to be a configuration issue with the "pyth-stuff/documentation" Vercel project rather than a code problem. The two Vercel projects may have diverged in their settings (Node version, build commands, environment variables, root directory, etc.).

Questions for maintainers:

1. Is the "pyth-stuff/documentation" Vercel project still intended to be active, or is it a legacy project?
2. If it's intended to stay active, could someone with Vercel access compare its configuration with the working "pyth-network/docs" project and align the settings?
3. If it's legacy, should we consider disabling/detaching its GitHub integration to prevent it from blocking PRs?

I don't have access to the Vercel deployment logs to see the specific error, but I'm happy to help investigate further if someone can share the logs or grant access.

Note: The page /price-feeds/pro/how-lazer-works builds correctly (verified in local build output), and the existing redirects in next.config.js will handle any legacy /lazer/* URLs properly.
