experimental: add CODEOWNERS for experimental/ skills

Owners are the top contributors to databricks-solutions/ai-dev-kit
(>=10 commits at import time). The cross-org team
@databricks-solutions/ai-dev-kit-maintainers is the canonical owner;
this line can be replaced with that team handle if the team gets
write access to this repo.

+# Experimental skills imported from databricks-solutions/ai-dev-kit on a
+# best-effort basis. The merge gate is the same as the rest of the repo
+# (the existing writers from the `*` line above) so changes here can't be
+# self-approved by a-d-k contributors.
+#
+# The top a-d-k contributors (>=10 commits at import time) are granted
+# repo-level write access so they can push branches and open PRs, but they
+# are deliberately NOT Code Owners on this path — that means their review
+# alone does not satisfy the Required-Code-Owner-Review branch protection.
+# They are the natural suggested reviewers for `/experimental/` changes:
+#   @calreynolds @dustinvannoy-db @malcolndandaro @auschoi96 @jacksandom
+#   @QuentinAmbard @NatyraB @jiteshsoni @scottDBX1886 @alexmillerdb
+# All confirmed Databricks employees via Slack lookup at import time
+# (Field Engineering / SSA / Strategy & Execution).
