ci: lift bot stage turn caps to ~10x — let timeout-minutes be the ceiling (#2538)

Premature optimization on a dimension we don't have data for. The
real ceiling is each workflow's `timeout-minutes` (5-60 min depending
on stage), and the real safety net is `WHEELS_BOT_ENABLED=false`.
Turn caps that compete with those ceilings just create a redundant
cliff, and tonight we discovered painfully that misjudging where it
sits costs a full failed run + manual cleanup + re-dispatch.

Math that motivates the lift: with `timeout-minutes: 60` and Opus at
~5-10s per turn, propose-fix can practically execute ~360-600 turns
before the timeout triggers anyway. A 100-turn cap was a cliff at
~17% of the time budget. A 1000-turn cap is unreachable — the
timeout catches it first, which is what we want.

Plan: run with these ceilings for a few weeks, collect data on
actual turn counts across a variety of issue shapes, then revisit
with empirical evidence rather than guesses.

  bot-triage:       20 →  200   (Sonnet, timeout 25m)
  bot-research:     40 →  400   (Opus, timeout 30m)
  bot-propose-fix: 100 → 1000   (Opus, timeout 60m — effectively no cap;
                                  workflow timeout becomes the ceiling)
  bot-write-docs:   30 →  300   (Sonnet, timeout 30m)
  bot-review-a:     25 →  250   (Sonnet, timeout 20m)
  bot-review-b:     30 →  300   (Sonnet, timeout 15m)

Worst-case incremental cost if a stage hits its new cap before the
workflow timeout: ~$50 for propose-fix Opus at 1000 turns, similar
for research. In practice the workflow timeout will catch any
runaway long before max-turns does. The kill switch
(`WHEELS_BOT_ENABLED=false`) is the manual safety net for active
incidents.

Subsumes both the original 30 → 50 single-stage write-docs bump and
the 2x audit. The 10x lift is the right level of generosity for the
data-collection period before we tighten anything.
