Release/3.0.1

[CassioMG]

Summary

Patch release rolling up the two correctness PRs landed since 3.0.0:

• Verify SEP-10 challenge body integrity after domain signing #237 — SEP-10: verify the auth server returns the same challenge body after client_domain re-signing instead of trusting a server-supplied transaction
• Correctness fixes: maxFee, 504 retries, key cache #238 — three independent correctness fixes:
  • submitWithFeeIncrease: forward maxFee across recursive retries so the cap is enforced on every retry, not just the first
  • submitTransaction: replace unbounded recursive 504 retries with a bounded equal-jitter exponential backoff loop
  • KeyManager.removeKey: actually delete the in-memory cache entry instead of leaving it stale

No public API changes. No new dependencies. SemVer patch.

Test plan

• yarn build — all 3 packages compile successfully
• yarn lint — zero warnings
• yarn test:ci — all suites passing on main post-merge
