feat(install): make LLM setup optional in web installer and CLI (#265)
## Summary

Makes LLM setup explicitly skippable in both the web installer and
`fabro install`, without making omission accidental. A skipped LLM step
lets install complete with zero LLM credentials; later LLM-dependent
workflows keep using the existing provider-not-configured behavior.
`fabro doctor` is intentionally unchanged.

Plan: `docs/superpowers/plans/2026-05-14-optional-llm-install.md`

## Key changes

**Server + API**
- `PUT /install/llm` now accepts `{"providers":[]}` as "LLM step
completed, skipped" — the empty-list rejection is removed; per-provider
validation for non-empty lists is retained.
- OpenAPI: dropped `minItems: 1` from
`InstallLlmProvidersInput.providers`, updated schema descriptions so
empty = skipped and `llm: null` = incomplete. TypeScript client
regenerated.
- `/install/finish` still requires the LLM step to be present, but
tolerates zero credentials — it writes settings, runtime auth secrets,
and GitHub secrets normally and writes no LLM vault entries.

**Web installer**
- New "Skip LLM setup" secondary action on the LLM step (via a
`secondaryAction` prop on `StepPanel`) that records an empty provider
list and advances to GitHub.
- Review screen shows `LLM providers: Skipped` (step completed, empty)
vs `Not configured` (step never completed), via a new
`describeLlmSummary` helper.
- Continue with no API keys still shows the existing validation error —
skipping is only reachable through the explicit skip action.

**CLI**
- Interactive `fabro install` asks "Configure LLM providers now?"
(default yes) before provider selection; declining returns an empty
selection and continues to GitHub.
- Hidden non-interactive `--skip-llm` flag, mutually exclusive with
`--llm-provider` / `--llm-api-key-stdin` / `--llm-api-key-env` via clap
`conflicts_with_all`. Missing LLM flags are still validation errors
unless `--skip-llm` is present. Non-interactive usage text updated with
a skip example.

## Code review

Ran a 12-reviewer `ce:review` pass (correctness, testing,
maintainability, project-standards, agent-native, learnings, security,
api-contract, reliability, adversarial, cli-readiness,
kieran-typescript). No P0/P1 findings; agent-native parity PASS. Applied
fixes in `40a29c591`:
- Re-entrancy guard on `runStepSubmit` so a fast double-click on "Skip
LLM setup" can't fire two requests.
- `validate()` only suggests `--skip-llm` in the missing-provider error
when no credential flag is set (it conflicts with those flags).
- Added tests: all three `--skip-llm` conflict arms, the review screen's
"Not configured" branch, and the skip-button failure path.

One advisory finding left as report-only: an empty `PUT /install/llm`
overwrites previously-saved credentials if a user navigates Back and
clicks Skip — judged acceptable since the button is explicitly labeled
and clicking it is deliberate.

## Testing

- `cargo nextest run -p fabro-server -p fabro-cli -p fabro-install` —
1521 passed
- `cargo build -p fabro-api`, `cargo fmt --check`, `cargo clippy`
(changed crates) — clean
- `bun test` (install-app) — 14 passed; `bun run typecheck` — clean
- New coverage: server accepts empty providers + session shows `llm`
complete with `providers:[]`; finish with skipped LLM persists no LLM
vault credentials but keeps GitHub secrets; web skip button PUTs
`providers:[]` and navigates to GitHub; review renders Skipped / Not
configured; CLI `--skip-llm` requires `--non-interactive`, conflicts
with all credential flags, `validate()` succeeds with `--skip-llm`,
usage text documents `--skip-llm`.

Not added (out of plan scope): an automated test for the interactive
`InstallInputSource` skip branch — `InteractiveInstallInputSource` is
TTY-coupled and has no existing tests; the non-interactive `--skip-llm`
path is fully covered.

## Post-Deploy Monitoring & Validation

This change is install-time only; there is no continuous runtime impact.
Validate during the next install/release smoke:

- **Web installer:** run a fresh browser install, click "Skip LLM setup"
on the LLM step, confirm it advances to GitHub and the review screen
reads `LLM providers: Skipped`. Finish the install and confirm the
server restarts into normal mode with no LLM credentials in the vault
(`secrets.json` has no credential entries) and
GitHub/server/object-store/sandbox settings written normally.
- **CLI:** run `fabro install --non-interactive --skip-llm
--github-strategy token --github-username <user>` and confirm it
completes; run interactive `fabro install` and confirm declining
"Configure LLM providers now?" continues to GitHub.
- **Healthy signals:** install completes (web `/install/finish` → 202;
CLI exits 0), server boots in normal mode, `fabro doctor` runs and
reports no LLM providers configured (expected, unchanged behavior).
- **Failure signals / rollback trigger:** install fails to finish,
server fails to boot after a skipped install, or `/install/finish`
rejects a completed-but-empty LLM step. Rollback = revert this PR;
install behavior returns to requiring at least one LLM provider.
- **Validation window/owner:** next install smoke / release
verification, owned by whoever runs the release.
