POST-018: post/put confirmations through the shared banner

be post and be put print their confirmations as raw fprintf to stderr — sniff: commit <hex>, N change(s), staged N put row(s), and the post ambiguous-message picker — bypassing the shared ROWS state banner (BE-005). Route them through ROWS so post/put speak the same banner + --tlv model as get/status.

Input

Context

• be post commit confirmation is fprintf(stderr, "sniff: commit <hex>") (SNIFF.exe.c:815); dry-run already uses ROWS (POST.c:2338).
• be put only prints sniff: staged %u put row(s) (PUT.c:1027); its per-file staged rows already stream via ROWS (PUT.c:712).
• Post msg-picker lists candidates with raw fprintf (POST.c:2439/2447).
• N change(s) summary tail (POST.c:2345) is a trailing stderr line.

Goals

• be post emits a commit ROWS row (verb=post, clickable commit:?<sha> — ROWS_NAV_COMMIT already exists) under the banner.
• be put confirmation rides the same banner (count in the banner / summary tail), not a bare stderr line.
• The ambiguous-message picker renders as banner rows, not raw tabs.

Constraints

• Depends on the BE-005 ROWS banner core. sniff/ only; no abc/.
• Keep genuine error/diagnostic chatter on stderr — only the report (data) lines move to the hunk stream.

WIP

Design decisions

• Reuse ROWSu8bFeedRec with ROWS_NAV_COMMIT (the tested ?<sha>#<subject> row) for the commit confirmation.
• Put's count becomes the banner/summary, mirroring status's tail.

TODOs

• Repro: be post/be put emit a banner-headed hunk (commit row / staged rows) in color & --tlv; no raw stderr report line.
• SNIFF.exe.c:815: commit confirmation → ROWS commit row.
• PUT.c:1027: staged count → banner/summary, not bare stderr.
• Post msg-picker (POST.c:2439) → banner rows.
• ctest -j16 green.

Blockers and bummers

• None yet.

Outcome

• (pending land)
