docs: README + CHANGELOG reflect Laravel bootstrap landed

Status table flips to 'bootstrap landed' with concrete next-step
pointers into INITIALIZE.md (Passport → step 2, Inertia → step 3,
multi-tenancy → step 4, etc.). CHANGELOG records every scaffolding
artifact that shipped this round + the platform.php pin rationale.

 ### Added
 
+- **Laravel 12 bootstrap landed** (`edfc845`, `059a60d`):
+  `composer create-project laravel/laravel . "^12"` ran; the
+  framework skeleton, PHPUnit, Vite, and Tailwind asset pipeline
+  are committed. `composer.json` carries Simtabi metadata
+  (`name`, `authors`, `support`). `config.platform.php = "8.2.0"`
+  pins lockfile resolution so the maintainer's PHP 8.5 local and
+  CI's PHP 8.3 / 8.4 runners generate compatible lockfiles.
+  `package-lock.json` committed so `npm ci` works in CI.
 - Initial repo scaffolding: README + LICENSE + CHANGELOG +
   CONTRIBUTING + SECURITY + CODE_OF_CONDUCT + `.editorconfig` +
   `.gitignore` (Laravel-aware) per Simtabi conventions.
-- `.github/workflows/{ci,release}.yml` matrices for PHP 8.3 + 8.4
-  on Linux + macOS, with Node 22 for asset builds.
-- `.github/dependabot.yml` weekly on Monday 06:00 America/New_York.
+- `.github/workflows/ci.yml` matrix for PHP 8.3 + 8.4 on Linux +
+  macOS, with Node 22 for asset builds. Bootstrap precheck makes
+  CI a no-op when `composer.json` / `package.json` are absent.
+- `.github/dependabot.yml` weekly on Monday 06:00 America/New_York
+  for composer + npm + github-actions.
 - `.github/ISSUE_TEMPLATE/{bug_report,feature_request,config}.yml`
   + `PULL_REQUEST_TEMPLATE.md`.
-- `docs/architecture.md`, `docs/api/v1.yaml` (OpenAPI 3.1 skeleton),
-  `docs/decisions.md` (ADR index).
+- `docs/architecture.md` (multi-tenant data model, OAuth flow,
+  background workers, signed-URL handoff),
+  `docs/api/v1.yaml` (OpenAPI 3.1 skeleton for `/tenants/me`,
+  `/registries`, `/audit`), `docs/decisions.md` (ADR index).
 - `INITIALIZE.md` documents the `composer create-project laravel/laravel`
   bootstrap + Passport + Inertia + React + tenancy steps in order.
 
 ### Not yet
 
-- The Laravel install itself (`INITIALIZE.md` is the runbook).
-- The multi-tenant data model migrations.
-- OAuth provider integrations.
-- The first real controller / route.
+- Passport (OAuth) install — INITIALIZE.md step 2.
+- Inertia + React + Tailwind asset pipeline — step 3.
+- Multi-tenant data model + migrations — step 4.
+- OpenAPI validator wired + controllers conforming to v1.yaml — step 5.
+- Pest swap from PHPUnit — step 6.
+- The first real `/api/v1/*` controller.
 
-When the bootstrap lands, that becomes the first `[0.1.0]` cut.
