Subject: [PATCH] fix: same-page transclusions with diff sections

When a page embeds two different sections from the same note (e.g.,
`![[Note#Section A]]` and `![[Note#Section B]]`), the second transclusion
is incorrectly flagged as circular. This happens because the `visited` set
in `renderTranscludes` tracks targets by slug alone, so the second embed
of the same file is treated as a cycle even though it references a
different section.

Include the block/section reference (`dataBlock`) in the visited key so
that different sections of the same page are treated as distinct
transclusion targets. Full-page transclusions (no section reference) still
use the slug alone, preserving circular reference detection for actual
cycles.
