Issue 27 — Pi ↔ Stellar protocol-version skew undocumented

[Junman140]

Labels: documentation, bridge, priority:medium
Body:

Problem
Pi Network (a Stellar fork) and Stellar mainnet are on different protocol versions and evolve independently (Stellar is now on Protocol 27 "Zipper," live since July 10, 2026). Nothing documents how the relayer/bridge handles differences in transaction/ledger format, fee structure, or SDK compatibility between the two chains.

Proposed fix
Add a COMPATIBILITY.md stating: which Pi Core version and which Stellar protocol version this bridge is built/tested against, how breaking changes on either side get detected (e.g., CI job hitting both networks' latest testnet), and an update policy.

Acceptance criteria

• COMPATIBILITY.md merged
• CI (or a scheduled job) checks both networks' current protocol version and flags drift
