* [x] Fixed an issue where embeddings would be assigned incorrectly to
files if a subset of embedding batches failed
* [x] Added a command to debug which paths are present in the semantic
index
* [x] Determine why so many paths are often missing from the semantic
index
* we erroring out if an embedding batch contained multiple texts that
were the same, which can happen if a worktree contains multiple copies
of the same text (e.g. a license).
