Use each channel's local balance minus its reserve when simulating Loop
Out payment bandwidth, clamping the result at zero. This prevents swaps
from starting when the gross balance covers the amount and routing fee
but the spendable balance does not.
Add one-sat boundary tests and a bug-fix release note. Leave a TODO for
server-fee and prepay capacity because enforcing their maximum fee caps
could reject viable swaps whose actual routing fees are lower.
Document every published Loop release and preserve authoritative notes.
Add the next-release workflow and rebuild chronological navigation.
Rename the reproducible-build guide for clarity.
