feat(ADR-0136.S.1): rate/event statement parsing — capacity + earnings shapes, axis lane 20/20, wrong==0, gsm8k-0014 admits (#201)
* docs(ADR-0136.S.0): refusal taxonomy + S.1 brief for rate/event statement corridor
Taxonomy: deterministic classification of all 50 GSM8K train-sample refused cases
into primary + secondary barriers. Key findings:
context_filler (primary): 23/50 — legitimately refuses; not parser gaps
compound_statement: 5/50 — two ops in one sentence
rate/capacity class: 4/50 — direct S.1 targets
distributive_multiply: 1/50 primary, 5/50 secondary
long-tail (diverse): 17/50
Honest S.1 ceiling: 0/50 → ≤4/50 admission. gsm8k-0014 ('Bob can shuck 10
oysters in 5 minutes') is the only case with capacity_rate as sole barrier.

* feat(ADR-0136.S.1): rate/event statement parsing — capacity + earnings shapes, axis lane 20/20, wrong==0, gsm8k-0014 admits
Two closed statement shapes added to candidate parser and graph:
Shape A (capacity-rate): "<Actor> can <verb> N <unit> in M <time-unit>"
- 13 closed verbs (shuck/pick/pack/make/produce/type/read/write/paint/run/score/answer/complete)
- Pronoun question form (he/she/they/it) accepted
- Time-unit conversion (second/minute/hour/day)
Shape B (earnings-rate): "<Actor> <verb> $N per/an/a <time-unit>"
- 5 closed verbs (make/earn/receive/get/charge)
- Currency: $ only, 0-2 decimal places
- Per-token alternation: per/a/an/for each/every
Short-circuit paths in parse_and_solve run before the Cartesian product,
computing rate_per_sec × T_seconds directly. Actor mismatch → refusal
(not wrong). Answer ≤ 0 → fall through to refusal.
GSM8K honest delta: 0/50 → 1/50 (gsm8k-0014: answer=240.0, correct).
23 context-filler cases correctly remain refused.
Axis lane: 20/20 pass, wrong=0.
B3 bounded-grammar lane: unchanged (wrong=0).
35 new tests including B3 regression guard and GSM8K admitted_wrong=0 rail.
