* fix: patch fastapi_mcp circular  recursion that blocks MCP endpoint registration
fastapi_mcp 0.4.0 resolve_schema_references() has no cycle detection.
Feast's OpenAPI schema contains self-referential protobuf types
(Value -> Struct -> Value) which trigger a RecursionError.  The error
is silently caught, so the /mcp route never gets registered and CI
gets a 404.
Add _resolve_schema_references_safe() that tracks a seen-refs set to
break circular  chains, and monkey-patch it into fastapi_mcp
before FastApiMCP processes the schema.  Non-circular schemas produce
identical output to the original.

* - Add GET /v1/vector_stores and GET
  /v1/vector_stores/{id} endpoints
    with RBAC enforcement (DESCRIBE permission)
  - Introduce VectorStoreRegistry cache that derives
  vs_{sha256} IDs from
    project + feature view name, refreshed on registry
  TTL cycle
  - Replace raw feature view names with stable vs_
  identifiers in search
    responses (file_id, filename fields)
  - Update docs, blog post, and integration tests for
  new ID scheme
  - Add unit tests for VectorStoreRegistry, ID
  generation, and object building

* docs: Fix dead Slack invite link

The "Come say hi on Slack!" link pointed at communityinviter.com, which has
been deprecated; the invite no longer resolves. Repoint it at the
https://slack.feast.dev/ vanity URL, which redirects to the current Feast
Slack workspace invite and stays valid as the underlying invite rotates.

Updated in both the README and docs/community.md (the source for the
docs.feast.dev/community page).

* docs: Update Slack link in README template

README.md is auto-generated from infra/templates/README.md.jinja2, so the
source template needs the same fix. Update it and regenerate; README.md is
unchanged since it already carried the corrected link. This also resolves
the template-consistency check that was failing on the direct README edit.

mcp_server used a module-level `from feast.feature_store import FeatureStore`
solely for a type annotation on add_mcp_support_to_app. Because the
feast.infra.mcp_servers package __init__ eagerly imports mcp_server, importing
the package pulled in the entire feature_store import graph. Under parallel
unit-test collection (pytest -n) this intermittently raced with an in-progress
feature_store import and failed collection of test_mcp_server.py with
`KeyError: 'feast.infra.mcp_servers.mcp_server'`.

Move the import under TYPE_CHECKING and use a forward reference, so importing
mcp_server no longer triggers the feature_store graph. Public API and the
annotation are unchanged.
