fix: gap-separated id lines and end-of-line caret expressions

Two review findings (pass 3) on the full-block text path:

- a block id alone on its own line, one blank line below the content,
  belongs to the block above it (Obsidian's gap form). getBlockText()
  now jumps back to that block before expanding, so the alias carries
  the real block text instead of falling back to the block id.
- the per-line trailing-id strip accepted a caret glued to content,
  eating e.g. the exponent of a line-final `2^10`. Obsidian only
  parses `^id` as a block id when it is whitespace-separated (or
  alone on the line) — the strip regex now requires the same.
