Test: add Cardano node startup check to Mithril Client multi-platform test workflow

[dlachaume]

Content

This PR includes enhancements for testing the mithril-client CLI across multiple platforms (Linux, macOS, Windows, and Docker), with or without ancillary files.

It also includes (Linux only and client binary):

• A verification step that ensures the Cardano node starts successfully after a snapshot restoration, by checking for the log line Started opening Immutable DB (with a 15s timeout).
• An optional check when restoration is configured with ancillary files, verifying that the log line Chain extended, new tip is present (with a 30s timeout).

LGTM, but I've a question: does the check against the cardano node is quick enough when running without the ancillary ? In that case the node must reconstruct the ledger and I fear that the added overhead make it too slow (plus maybe only checking with ancillary is enough ?).

You're absolutely right, without the ancillary, the ledger state reconstruction is time-consuming. That's why we've implemented two verification steps:

Without ancillary: We only check that the node starts opening the Immutable DB. This ensures that the necessary files are present to initiate the process. This check is quick and completes within the first 15 seconds.

With ancillary: In addition to the previous check, we verify that the node has received a new valid block, confirming that it's actively running and extending its chain.
