Update kagent 1.x reference docs at v1.0.0-alpha9 (version conrefs changed)

[github-actions]

Regenerates the kagent 1.x API and Helm references, its CLI and environment variable pages, and the version conrefs at a released tag. Nothing here was read from either repository's main:

• kagent: v1.0.0-alpha9 (6c4cfb2)
• kmcp: v0.4.0 (8f26f04)

The 1.x span of versions/kagent.md moves to 1.0.0-alpha9, so the helm install --version lines on those pages and the reference content beside them describe the same release. Only this line's spans were written; the other line's are asserted unchanged.

The environment variable reference is regenerated from docs/env.md in the kagent checkout, which upstream generates from the registry in go/core/pkg/env and holds to it in CI. The testing section is dropped as repository-facing; pass --include-section testing to publish it.

Important

A version conref moved in this run, so this is not a routine regeneration.
These values render into helm install --version lines that readers copy out of
setup/installation.md, observability/tracing.md, and observability/audit-prompts.md.
Merging asserts the guides work against the versions below, so re-test the affected
guides rather than merging on green CI alone.

Version conrefs in this run. Each is read from the same place kagent's own build reads it, at the tag above, except the two runtime images, which are resolved from the registry because a digest exists only once the image is pushed:

Conref	Value	Source
kagent (1.x span)	1.0.0-alpha9	the release tag this run documents
agent-substrate (1.x span)	0.4.0-alpha1	go/go.mod replace target
max-kube (1.x span)	1.35	Makefile KIND_IMAGE_VERSION
kmcp	0.4.0	go/go.mod require (what kagent bundles)
kmcp-latest	0.4.0	kmcp's latest release (what the kmcp guides show)
kagent-tools	0.3.0	helm/kagent/Chart-template.yaml
runtime-image	ghcr.io/kagent-dev/kagent/golang-adk@sha256:26ae5c772d4a59b24ecb3619c3499e106e3b28abbc239de25b4ff8d746f97e69	GHCR, at v1.0.0-alpha9
runtime-image-claude	ghcr.io/kagent-dev/kagent/claude-harness@sha256:e72d66d9f3b6eafbc59d18cef150fb5d31cb89ead83999a33c06264c21e86d4c	GHCR, at v1.0.0-alpha9

Unchanged conref values are normal: most runs touch only the generated reference pages.
