`_compute_heuristic_seq_id` ran `int(row[0])` directly on the result
of `MAX(e.seq_id)`. On palaces where chromadb 1.5.x has been writing
seq_ids natively (8-byte big-endian uint64 BLOB), that raises
`ValueError: invalid literal for int() with base 10: b'...'` before
the dry-run can print, leaving users with no path through the
recovery feature added in #1135 — the only documented un-poison
route for palaces hit by the original PR #664 shim bug.
Decode BLOB return values via `int.from_bytes(val, "big")` and
keep the existing `int(val)` path for INTEGER rows. Regression
test seeds a BLOB row in `embeddings.seq_id` and asserts the
heuristic surfaces the correct integer.
