- new behaviour in putMessage to handle grpc timeouts
- increase delays which triggered under significant loss

`cachix/install-nix-action@v30` uses the Determinate Systems Nix
installer which enables auto-optimise-store by default. This hard-links
identical store files to a shared `/nix/store/.links/<hash>` location.

On newer macOS, dyld resolves @loader_path using the canonical inode
path rather than the path used to exec the binary. So when a
haskell.nix-built binary (which links against `libHSghc-boot`
dynamically) gets hard-linked into `.links/`, dyld sees it as living
there and resolves `@loader_path` to `/nix/store/.links/` — making the
rpath `@loader_path/../lib/aarch64-osx-ghc-9.6.7` point to the
non-existent `/nix/store/lib/...` instead of the actual GHC library
directory.

Setting `auto-optimise-store = false` prevents the hard-linking, keeping
binaries at their proper store paths where `@loader_path` resolves
correctly.

Adds a fourth relay running 10.6.4 so the relay set covers every
producer version now that p1 is 10.6.4. relay4 mirrors the other relays:
mounts p1-configs, the shared relay-topology.json (dials all producers),
its own relay4-state volume, and the tracer socket. POOLS stays 4
(producers only). Docs updated.

Bumps p1 from 10.5.3 to 10.6.4. 10.5.x was the only version in the
cluster that still accepted the legacy Net.ErrorPolicy{,.Local} and
Net.Subscription.{DNS,IP} trace namespaces; 10.6.2/10.7.1/11.0.1 all
reject them and logged 'Illegal namespace' warnings every run.

With 10.5.3 gone, no node accepts those namespaces, so they are removed
from testnet.yaml outright (the configurator regenerates configs from it
at runtime — no image rebuild needed). Docs updated to p1 = 10.6.4.

Closes #157

  When partialFanout returns Left during the binary search fallback the
  error was silently discarded. Now emits PartialFanoutFailed with the
  reason before throwing StalePartialFanoutTx, making unrecoverable
  failures visible in the node logs.
