0.8.0

Added

• allow_failure for non-critical probes, named after the GitLab CI option: ProbeBase(allow_failure=True), @probirka.add(allow_failure=True) and the same keyword on every ready-made probe. Such a probe runs and is reported as usual, but its failure or timeout does not affect the top-level ok, so HTTP integrations keep returning success_code (#11)
• Group-level override: add_probes(..., groups='external', allow_failure=True) (or False) applies to every probe of the group, replacing the probes' own setting; None (default) keeps it. A probe run through several sources (the required list, several groups) is allowed to fail only if every source allows it. Passing allow_failure without groups raises ValueError (#11)
• ProbeResult.allow_failure (also in to_dict() and the HTTP JSON) with the effective value for the run (#11)
• Secrets are masked in health check output. Every ready-made probe registers the password of its connection string (as written, URL-decoded and as the Basic credentials httpx and aiohttp derive from user:pass@) and the values of its request headers, and ProbeResult.error has '***' wherever a client library echoed them. to_dict() additionally masks values of info under sensitive-looking keys (password, api_key, Authorization, ...) and passwords in URLs and ?token=-like query parameters in every string, error included. ProbeBase._register_secrets() does the same for custom probes; probirka.mask_url(), probirka.redact_value() and probirka.MASK are exported for your own handlers. See Secrets (#13)

Changed

• ProbirkaResult.ok is True when every probe without allow_failure passed; the overall timeout sets ok=False only if a probe without allow_failure did not finish, while error still reports the timeout (#11)
• to_dict() masks secrets by default; to_dict(redact=False) returns info and error exactly as produced. The HTTP integrations always return masked output (#13)
• All HTTP integrations render the body through the same json.dumps(..., default=...) call; the FastAPI adapter no longer uses fastapi.encoders.jsonable_encoder, which fell back to vars(obj) for arbitrary objects in info and thereby serialized their whole __dict__. Objects that are not JSON types are now written as their str() in every integration (#13)
