Allow every docker-php/docker-php-api line from 7.1.45 to 7.1.56. Detect
the installed line's version from the generated client and use it as
the default request version.

Without api_version or DOCKER_API_VERSION, the bundled factory now
negotiates: it pings /_ping once and uses the lower of the daemon's and
the installed line's API version, as the Docker CLI does. Connection
errors from the ping propagate instead of being retried.

Handle differences between the generated lines: accept the Accept
parameter added to systemEvents() in API 1.52, decode stats samples into
ContainerStatsResponse from API 1.48, and add FrameError::message() for
progress frames whose error field changed in API 1.52.

Decode integers above PHP_INT_MAX as PHP_INT_MAX. Docker reports
pids_stats.limit as the largest uint64 for a container without a PID
limit, and the generated integer setters rejected it as a float.

Throw for error statuses the generated endpoints do not handle, and
apply .dockerignore in build contexts, by default. Both keep an opt-out.

Run CI against every API line on the runner's daemon, which negotiates
the newest lines down, and the newest line against Docker 29.

BREAKING CHANGE: Composer installs the newest API line unless the
application requires one, and generated model names and fields differ
between lines. Require docker-php/docker-php-api >=7.1.45.0 <7.1.46.0 to
keep the 3.x models. Unhandled error statuses throw instead of returning
null; call throwOnUnexpectedStatus(false) to keep null. Context applies
.dockerignore; call applyDockerignore(false) to archive the whole
directory. Subclasses overriding systemEvents() need the new $accept
parameter.

Describe API line selection, version negotiation and the new defaults. Add a 3.x upgrade section and make examples work on every API line.

Add the 4.0.0 changelog and update the main branch alias.

API 1.48 renamed IdResponse to IDResponse. Pick the generated class that exists, since class files are looked up case-sensitively on Linux.

Most applications upgrading to 4.0 come from the original 2.x client or from beluga-php/docker-php 1.45.x. Link both from the docs home page, list them before 3.x in the upgrade guide and README, and point them to the 3.x changes, which also apply to them. Fix the home page card that still said 3.0.

Update mint to 4.2.992 and override the transitive versions that the latest Mintlify CLI still pins: axios, sharp, adm-zip, js-yaml 4, qs, katex, postcss-selector-parser, fflate and the MCP SDK. front-matter still needs js-yaml 3, which pulls in sprintf-js, and sprintf-js has no patched release.

The 4.0 client supports API v1.45 to v1.56, so link the reference index instead of the v1.45 page.

…essage before 1.16

Older Jane runtimes and php-http/message releases depend on the abandoned php-http/message-factory package. The client allows API package revisions that still accept them, so lowest-dependency installs pulled it in.

Add the 4.0.1 changelog.

Drop the funding entry from composer.json and .github/FUNDING.yml, which pointed to the Beluga maintainer's sponsorship pages.

Add the 4.0.2 changelog.
