chore: cap audit — remove distill rate cap, loosen size/budget gates

Plan-tune cathedral follow-up. The 3/day distill cap was theatrical: at
~$0.01 per Haiku call, even a runaway loop firing every minute would cost
~$14/day, and free-text events are rare enough that the natural input
rate self-limits to 1-2 fires/day. Count caps don't protect against
runaway bugs (which fire 1000x/second, not 4 times/day) but DO punish
heavy users who'd legitimately distill multiple times during a busy week.

Removed: 3/day rate cap on bin/gstack-distill-free-text. --status output
swapped from "TODAY: N / 3" to "TODAY: N run(s), $X" so users see what
they're spending instead of how close they are to a meaningless count.

Loosened (caps that exist for real-runaway protection, not normal scope):
- EVALS_BUDGET_HARD_CAP_GATE   $25 → $200/run
- EVALS_BUDGET_HARD_CAP_PERIODIC $70 → $500/run
- EVALS_BUDGET_HARD_CAP        $30 → $300/run (umbrella fallback)
- GSTACK_SIZE_BUDGET_RATIO     1.05 → 1.50 per-skill ratio
- plan-review preamble byte budget 40K → 60K

Principle: caps exist to catch obvious bugs (infinite retry, model price
change, prompt blowup), not to gate legitimate scope growth. Set high
enough that real growth never trips them, only bug territory does.
Adjusted defaults are 4-8× historical worst case, leaving ample headroom
for the next 12 months of legitimate expansion.

Tests updated: distill-free-text removes the 3-test rate-cap describe
block in favor of "no rate cap" assertion that 10 runs/day pass. Other
budget tests still pass because they were never near the old ceilings.
