feat(docs): add root docs/ symlink to packages/docs/src/content/docs/

Add symbolic link at repository root pointing to documentation content in
packages/docs/src/content/docs/ to match pattern from infra/ repository.

This makes documentation easily discoverable from the repository root while
maintaining the monorepo package structure. The symlink uses a relative path
for portability across different environments.

Also moves existing docs/notes/ directory to packages/docs/src/content/docs/notes/
to preserve working notes within the unified documentation structure.

Pattern: docs -> packages/docs/src/content/docs/
