fix(cli): set up unconfigured workspaces on start

[NicholaiVogel]

Summary

Unconfigured Signet workspaces now enter setup during daemon start, restart, or dashboard launch instead of failing before users can initialize them. Database-bearing workspaces missing manifests use recovery setup that preserves existing database contents. The curl installer also supports installing the latest nightly directly with --nightly.

Changes

• Route fresh workspaces and eligible incomplete workspaces through interactive setup before daemon startup; retain the non-interactive signet setup guidance.
• Repair workspaces that have a database but lack both manifests, using the workspace-layout-aware database path for legacy and v2 layouts.
• Add --nightly to the curl installer; resolve the nightly version, select its release assets, and forward other installer arguments unchanged.
• Document stable and nightly curl installation commands.

Type

• fix — bug fix

Not applicable: this change modifies CLI setup and installer documentation, not a UI.

Focused checks passed:

• bun test surfaces/cli/src/features/setup-recovery.test.ts surfaces/cli/src/features/daemon.test.ts platform/core/src/workspace.test.ts scripts/install-shell-compat.test.ts — 55 passed.

• bash -n web/marketing/public/install.sh and zsh -n web/marketing/public/install.sh
• git diff --check

bun test surfaces/cli/src/features/setup.test.ts reports 43 passed and 2 failed on both this branch and origin/main: one existing onboarding test expects a dynamically allocated server port but receives the default port, and the related unavailable-workspace case times out. These failures reproduce on the unchanged base.

Notes

bun scripts/doc-drift.ts exits 1 on both origin/main and this branch because the API reference lists 35 routes not found by the current source inventory; this change does not modify API routes.
