clawbot c737490a53 Compute the content hash only when head and tail match (closes #61)
check / check (push) Successful in 49s
A file of 10 MiB or more now gets only its 64 KiB head and tail in the
hash phase, so its content is read only when it can be a duplicate. A
new content phase after the update phase finds every group of records,
anywhere in the database, that share size, head and tail and include
one without a content hash. It checks every member with lstat and, when
at least two pass, reads those without a content hash through the
existing worker pool; a stale file does not count as a match. report
and trees leave out records without a content hash. The README, help
text and TODO entry describe the gate; the schema stays at version 1.

Lint suppressed: gosec on the file open in hashContentOnly, as in
hashSignature, and on one chmod in a test.

Model: opus-5-5

sneak 7a6adae0d2 Add test suite covering parsing, grouping, digests, and scan passes
Covers splitNUL framing, parseScanStream (malformed records, tabs and
newlines in paths, unterminated trailing record), duplicate grouping
with ordering/tie-break/determinism, humanBytes units, Merkle digest
equality and name/content sensitivity, maximal-tree suppression
(including sibling and differing-parent cases), hashHeadTail edge
sizes and error paths, walkPass .zfs/symlink skipping, statPass
vanished files, and an end-to-end walk/stat/hash pipeline test of the
README smoke-test scenario. 64% statement coverage.
