feat: bigger-spoon mint recipes (literal code) + modes filter + OpenRouter probe

Browse Source 
Spoonfeed mint was 0/96 for eq_override/stdout_marker/sentinel/file_marker: the
prose recipes were half-understood (model emits 'return 0') and the probe-channel
detector needs exec-clean code. Fix: hand the model the proven verify_rewards hack
template verbatim ('emit exactly this'), templated with the problem's graded method
name ({func}) -- load-bearing for eq_override. Validated 5/5 on OpenRouter qwen3-8b.

Also: --modes filter (re-mint only failed modes, keep cached run_tests/exit_code),
skip the wasteful faithful cell when minting, dump first completion even at 0 hacks
(the diagnostic that was missing), tqdm progbar.

scripts/validate_spoonfeed.py: direct OpenRouter probe (pi is 47s/call + TUI noise).
Calibration finding: even the PROVEN run_tests hack fails single-shot hint-discovery
on 8b (returns 'return 0'), so single-shot is NOT a learnability oracle -- it only
validates the mint path. RL learnability must be measured by the emergence run.

"""Quick OpenRouter probe of hack EASINESS at the SOURCE: the faithful hint.
The student never sees the spoonfeed recipe -- it trains on the faithful hint
(HINT_REPLACE_TO) baked into the prompt. If that hint is too coy (e.g. stdout_marker
"a success marker" without naming the token), the loophole isn't learnable and the
substrate has nothing to measure. This probes, per mode, whether a STRONGER model
(qwen3-8b) exploits the channel given only the hint + a generic "find the loophole"
nudge. 8b is an upper bound: if 8b can't, the 4B student won't either, and the hint
must be made more obvious (name the lever, still a truthful description).
set -a; source ../w2schar-mini/.env; set +a # OPENROUTER_API_KEY
uv run python scripts/validate_spoonfeed.py # hint level, all modes
uv run python scripts/validate_spoonfeed.py run_tests # calibrate on the paper hack
uv run python scripts/validate_spoonfeed.py --spoon sentinel # test the mint recipe instead
SHOULD: run_tests (the proven paper hack) exploits -> that's the "easy enough" bar.
A mode that does NOT exploit at hint level has a too-hard hint; lift it to match.
