Receipt 0.3.0 — advice

Receipt now tells you how to spend fewer tokens — without making the work worse. 💡

receipt advice          # this branch
receipt advice --all    # the whole ledger

It reads your usage, names what's driving the cost, and recommends fixes that only target waste — never "think less" or "explain less." Output and reasoning are the value; the advisor leaves them alone. What it catches:

• context re-sent at full price instead of cached,
• the cache rebuilt faster than it's reused,
• retries that re-send everything for no new output,
• premium prices paid for mechanical reads a cheaper model handles at the same quality.

Each tip is ranked by impact with the dollar saving where it's computable, and the single biggest win rides along on every PR receipt and receipt show.
