Summary

Fix unwrap You Receive to net Classic InstantWithdraw burn tax after wrap-mapper fee_bps (10 000 @ 200 bps + 1.5% → 9 653, matching mainnet evidence).
Fix wrap display over-deduction: wrap_deposit is untaxed MsgExecuteContract — quote mapper fee only (10 000 → 9 800, not ~9 751).
Disclose unwrap burn tax on the fee line; warn against exchange deposit recipients.
Keep router minimum_receive on post-fee pre-tax (routerMinReceiveBase / R3).
Document invariants W8–W11; add skills/AGENTS_WRAP_UNWRAP_BURN_TAX.md + make verify-issue-512.

Closes #512 (UI/disclosure + accurate quotes). On-chain InstantWithdraw gross-up remains a ustr-cmm follow-up.

Test plan

make verify-issue-512 (unit + docs) — passed twice
Manual mainnet: wrap 10 000 LUNC → quote 9 800 cLUNC
Manual mainnet: unwrap 10 000 cLUNC → quote ~9 653 LUNC; fee note mentions burn tax
Unwrap UI shows exchange-deposit warning on Swap + /wrap
Native-output swap still submits minimum_receive from post-fee base (no false R3 reverts)
