test+docs: live mainnet burn e2e verified; treasury rent-exempt requirement

End-to-end burn proven on mainnet (test wallet): build → sign → broadcast →
confirm → receipt → Essence. tx 5ddbmLRz… burned a dust token, closed the
account, returned 0.00197 SOL to the user, sent the 5% (103704 lamports) to the
treasury, recorded as Essence (Round #1 = 103704). Re-scan confirms the account
is gone; treasury credited; DB row written.

Discovered + documented: the treasury must be funded to rent-exemption before
collecting fees (a fee transfer into a 0-balance account fails "insufficient
funds for rent"). Noted in .env.example + design §3.1. Tracker: Phase 3 done.
