docs: sync documentation for v1.0.0 freeze

Mark LanguageRef as normative, add docs index, update README/Packages/
Stdlib/BuildAndTest status lines, archive PLAN.md and QUALITY_PLAN
pointers to RELEASE_v1.0.0 and active SEMVER.

 # Bux Language Reference
 
-This document describes the Bux programming language as implemented by the bootstrap compiler.
+> **Status:** Normative for **v1.0.0** (language freeze).  
+> Describes Bux as implemented by the **bootstrap** (`buxc`, Nim) and **self-hosted** (`buxc2`) compilers.  
+> Behaviour here is the contract for semver after 1.0 — see [`SEMVER.md`](SEMVER.md) and [`RELEASE_v1.0.0.md`](RELEASE_v1.0.0.md).
+
+This document is the primary language specification. Compiler bugs that contradict
+it are fixed without a MAJOR version bump; intentional breaking changes require MAJOR.

 # Bux Standard Library
 
-The Bux standard library provides core functionality for systems programming. All modules are merged into every compilation, so no explicit linking is needed.
+> **Status:** Documented API for **v1.0.0**. Sources live under `lib/`; modules are
+> merged into every compilation (no separate link step for stdlib).
+
+The standard library targets systems and cloud-on-Linux programming (I/O, collections,
+net/TLS with full runtime, crypto, tasks/channels). Thin/static builds use
+`BUX_RUNTIME=minimal` — see [BuildAndTest.md](BuildAndTest.md).
