On save, whitespace-prefixed `#hashtags` in a node's body are unioned
into its tag set (via `frontmatter.hashtags` + the existing tag diff), so
you can tag a note by writing `#kitchen` inline. A markdown `# heading`
has a space after the `#`, so it never matches. e2e covers it.

Node buffers now open with the editable YAML frontmatter block on top
(node.get {frontmatter: true}); on :w, `frontmatter.lua` parses the
block, diffs it against what was rendered, and routes each changed field
to the right RPC:
- title → node.update rename
- attention → task.set_attention
- do_date/late_on/recurrence → task.set_schedule (YYYY-MM-DD → local-ms;
a removed line clears via null)
- project → task.set_project (resolved by name)
- tags → tag.add / tag.remove
A mistyped state surfaces the daemon's validation error; a buffer with no
block edits no metadata (deleting the block can't wipe tags). Body rides
node.update as before (the store strips any echoed frontmatter).
Body-position features are content-relative, so the prepended block
doesn't disturb them; e2e specs that targeted absolute line 1 now locate
body lines by content via a new `h.find` helper. New frontmatter_spec
covers render + the full diff→RPC round-trip. 21 nvim e2e specs green.
