v1.6.0

This release fixes the ways agent connections could break and stay broken.
Each item links to its commit, where the full reasoning lives.

• Updating the wallet no longer disconnects your agents.

  The bridge used to require the wallet to be the exact same build, so any
  update cut off every connected agent — even updates that changed nothing the
  bridge could see. It now checks a compatibility version that only moves when
  the two actually need to change together. Note that this takes effect for
  updates after 1.6.0; installing this release will still end sessions
  started against 1.5.0.

• The wallet repairs its own agent helper.

  If the small program your agent runs to reach the wallet was replaced by
  another build, every agent silently stopped working and the only fix was
  removing and re-adding the connector. The wallet now notices and puts the
  right one back.

• Building from source no longer breaks your installed wallet.

  Running the test suite could overwrite that same helper with a development
  copy, breaking agents on the machine until something replaced it. Only a
  running wallet may touch it now. This affects contributors; installed
  wallets were never the cause.

• Complexity limits in CI.

  A guardrail against any single function quietly growing past the point where
  it can be reviewed properly.

Warning

Windows and Linux key-storage warning: The current builds use per-user credential services that do not isolate raw account keys or the database key to Ekubo Wallet. Same-user malware, including a prompt-injected local agent that can execute programs, can extract those keys and bypass wallet policy and review. Read the security model before installing.
