FreeBank v0.1.0 — M1 package

FreeBank v0.1.0 — M1 package release

First public release. FreeBank is a BIP 300/301 credit-creation sidechain: bills of
exchange with a consensus-enforced escrow bond, in the lineage of Scottish free banking.

Proven in this release (regtest, unit + integration gates):

• Full peg cycle on both mainchain transports — BMM advance, M5 deposit crediting, and the
  complete withdrawal payout (M3 bundle → M6 payout → funds received on the mainchain),
  including against the CUSF bip300301_enforcer (≥ upstream 6fdb827).
• Bills of exchange lifecycle on-chain: issue → endorse → retire/default, with escrow claim.

Network parameters (locked for this release): sidechain slot 130, magic
fb4b1845, port 8455, bech32 fbk; the main network pairs with a CUSF-enforcer
mainchain (L2L Signet era) and uses the enforcer's BlindedM6 withdrawal-bundle layout.
