Description: Adds a blog post announcing the experimental Feature View Versioning capability introduced in #6101, highlighting that it's still experimental, SQLite-only for versioned online reads, and inviting community feedback. Also adds agent/skill conventions to enforce blog post placement, and consolidates all agent instructions into AGENTS.md as the single source of truth. What this PR does / why we need it: infra/website/docs/blog/feature-view-versioning.md — New blog post covering: Hero image (feast-feature-versioning-hero.png) matching the style of other blog posts Hyperlink to the original feature request issue #2728 in the opening paragraph Two motivating use cases: (1) fixing forward on a live production feature while retaining a recoverable audit trail, and (2) offline experimentation with staged publishing before promotion to production Why production AI serving and point-in-time correctness is the primary motivating challenge Auto-versioning mechanics (feast apply auto-increments on schema/UDF changes, idempotent on no-change) Multi-version online serving via @v syntax (e.g. driver_stats@v2:trips_today); unversioned requests default to the latest promoted version Safe rollback via version pinning (version="v1" in the FeatureView definition) Staged publishing with feast apply --no-promote Why per-version online tables are necessary — explains why a single shared table was rejected and how isolated per-version tables are the only design that guarantees point-in-time correctness Client responsibility — clients default to latest promoted version; explicit @v pinning is opt-in Materialization complexity and tradeoffs — correctness challenges, per-version table ownership, storage/freshness costs, concurrency edge cases Known limitations: SQLite-only for versioned online reads, no offline versioning, no version pruning AGENTS.md (new) — Repository-level instructions for AI coding agents, synced with the full content from CLAUDE.md (dev commands, project structure, code style, contributing guide) plus the blog post placement convention: blog posts must go in /infra/website/docs/blog/ only CLAUDE.md — Replaced with @AGENTS.md so it points to AGENTS.md as the single source of truth for agent instructions skills/feast-dev/SKILL.md — Added a "Documentation and Blog Posts" section enforcing the same blog post placement convention Which issue(s) this PR fixes: Checks I've made sure the tests are passing. My commits are signed off (git commit -s) My PR title follows conventional commits format Testing Strategy Unit tests Integration tests Manual tests Testing is not required for this change Misc Blog post is intentionally scoped to what's implemented today. The call-to-action for community feedback on additional online store support is deliberate per the issue brief.
