fix(install): restore mode-specific step routing

[RerankerGuo]

What changed

• let mode-specific installer steps reach their dedicated should_skip_step cases
• preserve Keep-All upgrade behavior in each dedicated case
• add a focused shell regression test for Quick Start, non-interactive, Embedded, Keep-All, and manual routing

Why

Bash case statements stop at the first matching pattern. The Keep-All pattern also listed step_manager_runtime, step_e2ee, step_docker_proxy, step_idle, and step_hostshare, so their later mode-specific cases were unreachable.

As a result, Quick Start did not skip four advanced prompts, the non-interactive routing contract failed for five steps, and Embedded mode did not skip Docker proxy configuration at the router level. Some step functions had defensive non-interactive guards, but Quick Start still reached interactive prompts and the routing helper contradicted its own rules.

Validation

• the new test against origin/main fails 10 assertions (19/29 pass)
• bash install/tests/test-step-routing.sh passes 29/29 on this branch
• bash -n passes for every tracked shell script
• ShellCheck error-level scan passes for both changed scripts
• git diff --check

CI attribution for head 34a3b2a, workflow run #1668:

• Translation, change detection, the controller image, and all six downstream image builds passed.
• I inspected the raw logs for all 10 failed integration jobs. Every job has exactly one empty AGENTTEAMS_LLM_API_KEY, one LLM API Key is required installer error, make test-embedded exiting with error 2, and zero integration-test start markers.
• The installer stops in step_llm, before it reaches any of the mode-specific steps changed by this PR.

The remaining red checks are therefore the fork-secret bootstrap issue addressed by #1026, not a branch-specific failure. Locally, the focused routing regression fails 10 assertions on origin/main and passes all 29 assertions on this head; repository-wide shell syntax and changed-file error-level ShellCheck also pass.

The installer routing bug is real, but the PR is not ready yet. The new test loads should_skip_step through source process substitution; on the supported macOS Bash 3 environment that producer races with source, so the function is missing and 23 assertions fail. Please change the test to load the function synchronously in a Bash-3-compatible way, rerun it on macOS and Linux, and update the branch so the currently failed required integration checks are green before final review.
