chore: promote dev to main

[devchaudhary24k]

Summary

Promotes the latest dev branch to main.

This release combines:

• fix: enable PostHog web analytics #6 — restores PostHog Web Analytics
• feat: rename product to EnvSift #8 — renames EnvKit to EnvSift and moves product references to envsift.damnlabs.com

EnvSift rebrand

• uses EnvSift consistently for the visible product name
• keeps lowercase envsift for URLs, slugs, package names, filenames, storage keys, and analytics identifiers
• updates application metadata, documentation, PWA manifest, SEO text, and the product mark
• changes the canonical product URL to https://envsift.damnlabs.com
• updates source links for the planned repository name pixelactstudio/envsift

PostHog Web Analytics

• captures SPA page views and page leaves
• enables heatmaps and Web Vitals
• preserves the SDK properties required by those automatic events
• keeps autocapture, session recording, and exception capture disabled
• does not capture pasted ENV contents or form input values

Validation

The source PRs passed:

• analytics tests
• typecheck and lint
• application checks
• production build
• repository CI and Cloudflare Pages deployment checks

Note

Rebrand app from 'EnvKit' to 'EnvSift' and expand PostHog analytics

• Renames all user-facing references, package name, URLs, logos, PWA manifest, and site config from EnvKit to EnvSift.
• Expands PostHog analytics to emit page views (on SPA history changes), page leaves, heatmaps, and Web Vitals via a new AUTOMATIC_EVENTS whitelist in analytics.ts.
• Behavioral Change: theme preference previously stored under envkit-theme will not carry over — users will revert to the default theme on first load.
