refactor(machine): canonical sat-amount vocabulary + fix 100× fee bug
Aligns lamassu-next with the canonical sat-amount vocabulary agreed across lnbits/bitspire/satmachineadmin (satmachineadmin@d717a6e, coordination log 2026-05-26T17:10Z): - `feePercent` / `cashInFeePercent` / `cashOutFeePercent` → `feeFraction` / `cashInFeeFraction` / `cashOutFeeFraction` (canonical: unit fraction in [0, 1], NEVER a percentage) - `cashInFeeRate` / `cashOutFeeRate` (config option names) → `cashInFeeFraction` / `cashOutFeeFraction` - `fee_percent` (wire field on Payment.extra + state.db column) → `fee_fraction` Bug fix bundled with the rename: `lightning.ts:780` previously stamped `Payment.extra.fee_percent = context.feePercent * 100` (0.05 → 5.0). state.db stored the unit fraction (0.05) but Payment.extra carried the percent (5.0) — 100× divergence that any consumer reading Payment.extra computed fees wrong by exactly 100×. Now stamps `fee_fraction` directly as unit fraction. Display layers (atm-tui, view components) multiply by 100 themselves. Defensive invariants added: - `computeFeeSats` (atm store) throws if `feeFraction` outside [0, 1] or if cash-in `feeSats > principalSats` (would mean negative payout) - `recordTransaction` (state-store) throws on the same range - state-machine + electron + Vue views propagate the rename state.db migration v6 → v7: `ALTER TABLE transactions RENAME COLUMN fee_percent TO fee_fraction`. Historical migrations preserved verbatim (they wrote `fee_percent`, future installs see the same sequence followed by the v7 rename). 12/12 typecheck + 18/18 state-machine tests green. Coordinated with ~/dev/bitspire/atm-tui (separate commit) reading `fee_fraction` from the new column. refs: log:2026-05-26T17:10Z, log:2026-05-26T18:50Z, satmachineadmin@d717a6e Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
