v0.2.5

All six crates released together at 0.2.5. The version is the workspace's, so they move as one.

Crate
ytsaurus-yson	YSON codec, text and binary
ytsaurus-job	job runtime
ytsaurus-client	HTTP API v4 launcher
ytsaurus-helpers	#[derive(TableRow)] — first release
ytsaurus-skiff	Skiff schema and codec — first release, pre-release
ytsaurus-format	DataFormat — first release, pre-release

ytsaurus-skiff and ytsaurus-format carried publish = false until now. They are on the registry because ytsaurus-job and ytsaurus-client depend on them and could not be published otherwise; the Skiff ship gates are still not all green and their API may change in a patch release.

What is in it

Making a managed installation runnable from the environment (#50) — nine issues found by running the whole example suite against a real multi-node cluster instead of a local Docker one.

• Client::with_heavy_proxies_under(domains) — the configured address's domain plus the ones named. An installation that publishes its heavy proxies in a zone of its own had every one of them refused, and the only answers were writing all 79 names out or removing the rule.
• Four new Client::from_env variables — YT_PROXY_SUFFIX, YT_HEAVY_PROXY_DOMAINS, YT_HEAVY_PROXIES_ANYWHERE, YT_FILE_CACHE — each inert when unset. Every example builds its client with from_env, so a policy settable only in Rust is a policy an example cannot be run under.
• invalid peer certificate: UnknownIssuer now names the two things that fix it, YT_CA_BUNDLE and the platform-verifier feature.
• Both /hosts refusals offer all three settings with their environment spellings, and name a domain that could not be used rather than dropping it in silence.
• cached_upload brings its own file cache; profile builds its caption from the run and defaults to five rounds.
• Docs: a runbook for a cluster that is not the local one, a full environment-variable table, --features tls for selfrun against https, and the decoding share recorded as open — 10.6 % on a local cluster against 36.2 % on a production one, either side of the 30 % threshold the Skiff question turns on.
