oracle corpus: the ABI-o1 cell stages the published 1.5 plugin (plugins_line, as the pinned generator emits it)

[MattJackson]

Row 86 (oracle byte-identical to 1.5.5). This adds the one corpus line the pinned generator emits and predev's committed cells.json lacked.

Cause. busbar-oracle cells --check at predev's own engine (busbar-release 4a7a7bba2c) refused the corpus. builders_capture.rs json_plugin_cells gives plugins.abi|json-contract|store-sqlite the field "plugins_line": "1.5", because the published 1.5.5 store-sqlite plugin is that cell's subject for every binary judged. Without the field, a 1.6 build asked fetch-plugin for a 1.6-line asset ("no pinned asset for store-sqlite on x86_64-unknown-linux-gnu for busbar line 1.6"). The cell recorded nothing (missing.candidate), and ABI-o1's premise, which probes this cell, could not be evaluated.

Change. That one line, byte for byte as the generator writes it. cells --generate now differs from the committed file only by the three neutrality|routes|*-shaped-404 cells and their counts, which #493 adds together with D-1's scope count. The shepherd confirmed #493's file is the generator output minus this line, so the two merge cleanly. No golden, accepted difference, engine pin or code changes.

Proof (Latchkey large, full-corpus record and strict replay against golden/1.5.5, engine 4a7a7bba2c):

• this branch b1c580d (job cli-d6e10b29): 211 FAIL / 890 PASS / 1494 UNBASELINED;
• predev 7356bbf (job cli-a53d9b5f): 212 FAIL / 889 PASS;
• the one cell that moved is plugins.abi|json-contract|store-sqlite, FAIL (missing.candidate) -> PASS;
• no cell regressed: the FAIL set is predev's minus that one.

No Rust crate is touched, so there are no crate tests, clippy or fmt legs.

Superseded by #594, per ARCHITECT ruling 2026-10-07 option (b). The ABI-o1 cell moves to a new id, plugins.abi|json-contract|store-sqlite@1.5-line: the old id is retired whole with a citation, and the new one is golden-added from the published 1.5.5.
