fix(controller): move a ModelConfig condition's transition time only on a status change - #3340

)

kagent-dev#3340 files the Harness conditions (Ready from the WorkerPool,
Booted from the golden boots); the status merge patch files on its own later.
The git fetch retry rows wait for kagent-dev#3099, which rewrites
CloneGitCommit, and carry the notes for the re-cut; the durable copy is
superseded by kagent-dev#3099's task-time skill install. The SKILL.md frontmatter row
points at google/adk-go#1957 and kagent-dev#1958.

Remove `Harness.status` and the derived gRPC/UI readiness field, plus
ADK `network`, `share_tools`, and `ADKNetworkConfig`. Harness status has
no writer on main, and neither ADK consumes these config fields, so drop
them before the first RC.

Regenerates the CRDs and clients and removes the obsolete status RBAC,
fixtures, and tests. The removed protobuf fields have no reservations,
since this is the final pre-RC API break. Includes narrow Buf exceptions
for these removals.

Validated code generation and compatibility checks, focused Go/CRD
tests, Go lint, 87 Python config tests, 697 UI unit tests, UI
typecheck/lint, the Harness flow in Chromium and Firefox, and 21 Helm
RBAC tests.

Overlaps with kagent-dev#3340, which adds writers for the Harness status being
removed here.

Backports seven PRs from `main` to `release/v1.0.x` for the 1.0 release.
Each is cherry-picked with `-x` in its original merge order, and none
needed changes. Every file these commits touch now matches `main`
exactly.

| PR | Commit | Why |
| --- | --- | --- |
| kagent-dev#3558 | `2e2acf58c` | fix(ci): restore upgrade tests from RC3 |
| kagent-dev#3545 | `7c9c52105` | fix(ui): show when the Substrate lists were
read, not a running age |
| kagent-dev#3395 | `aaf1ca882` | feat(session): revert crashed runtimes through
RevertSession (needed for a customer) |
| kagent-dev#3562 | `5c490d83b` | refactor: remove helpers orphaned by the KMCP
removal (low risk; keeps the branch close to `main`) |
| kagent-dev#3563 | `c6adf72f9` | refactor(api): move MCP header resolution out of
`v1alpha3`, so the 1.0 API package describes only data |
| kagent-dev#3340 | `347acbe55` | fix(controller): move a ModelConfig condition's
transition time only on a status change (labeled `cherrpick-1.0`) |
| kagent-dev#3560 | `ccb2dd350` | adk/mcp: defer tool discovery until invocation,
so slow MCP discovery no longer fails agent resumes |

Please use **Rebase and merge** so each backported PR stays its own
commit on the release branch.

Validation before kagent-dev#3560 was added (CI covers the full set):
- `go build ./...` and `go vet ./...`
- `go test -race` with envtest for `api`, `core/cli`,
`core/internal/{controller,database,grpcserver,mcp,service,substrate}`,
`core/pkg/migrations`, and `pkg/logging`
- `make -C go lint`: 0 issues
- UI `tsc --noEmit` and `substrateReadAge.test.tsx`
