kevinveenbirkenbachandClaude Opus 5 0f450722bc feat(ci): start chunk 0 at the head, or wherever the operator points
The regular rows began wherever (sweep * capacity) % count pointed. On run 210
that was offset 68: chunk 0 opened at candidate 69, the coverage-first head of
the list went undeployed, and no two runs could be compared because the window
moved with the run number. A run that looked wrong turned out to be merely
rotated, and finding that out meant recomputing the arithmetic by hand.

The rotation is gone. Chunk 0 reads the ranking from the top unless an offset
says otherwise, and the offset is an input now, threaded from the manual form
through the orchestrator and the deploy call down to the matrix builder. The
plan renderer takes the same flag, so the table shows the window the run will
take.

The offset is a row count or a selection token. A token is the honest form:
the ranking shifts whenever a variant appears, so 'offset 84' means something
different tomorrow while 'web-app-nextcloud#5' still means the same row. Axes
the token leaves open match anything, so a bare role name starts at its first
row and a pasted job label starts at exactly the job it names. A token that
matches no regular row aborts rather than silently starting at the head an
operator meant to skip.

The run title carries it as ⏩ followed by the value, and only when one was
asked for, so a rotated-looking run says so in its own name and the retrigger
reads it back from there when a job log has expired.

resume_from_chunk leaves the manual form with it. Skipping whole chunks was
the coarse way to say 'carry on further down'; the offset says it exactly and
keeps the rest of the chain intact. The orchestrator input stays for the other
entry points.

What this gives up is automatic tail coverage. Rows beyond the budget are
reached by moving the offset, widening the budget or narrowing the selection,
not by waiting for consecutive sweeps to walk the list.
