release: promote Rezi to beta (v0.1.0-beta.1)

[RtlZeroMemory]

Summary

Promotes Rezi from alpha to beta and prepares the v0.1.0-beta.1 release.

• README rewritten for the beta line: status and versioning policy, requirements with the prebuilt binary matrix, architecture overview, and contribution entry points
• ROADMAP refreshed to reflect shipped work and the path to 1.0 (Beta → Toward 1.0 → After 1.0)
• Docs status wording updated from pre-alpha to beta across the docs index, widget stability pages, protocol versioning notes, and constraint guides
• jsx: parity tests pin the JSX component surface to the ui.* factory surface in both directions (plus index re-export coverage), so the hand-maintained wrapper layer cannot drift silently
• testkit: declares Bun support (bun >= 1.3.0) in engines, matching the other runtime packages
• release prep: all workspace and template versions set to 0.1.0-beta.1 via scripts/release-set-version.mjs, lockfile synced, changelog entry added

Validation

• npm run build clean
• new jsx parity tests pass (3/3)
• npm run lint clean (987 files)
• npm run check:create-rezi-templates OK
• npm run typecheck OK

Release steps after merge

git tag v0.1.0-beta.1
git push origin v0.1.0-beta.1

Per docs/dev/releasing.md: do not mark the GitHub release as a prerelease; the workflow publishes with the latest dist-tag.

Changelog entry and engine support CHANGELOG.md, packages/testkit/package.json	Documents the 0.1.0-beta.1 release with notes on alpha-to-beta promotion, documented API stability, testkit Bun runtime requirement (>= 1.3.0), JSX parity test coverage, and beta-focused documentation refresh.

Documentation Updates for Beta Status

Layer / File(s)	Summary
README and ROADMAP restructuring README.md, ROADMAP.md	README reframes Rezi from pre-alpha to beta, updates installation narrative, adds templates enumeration, and introduces a packages table with descriptions. ROADMAP restructured from Alpha/Beta/Stable phases to Beta (current)/Toward 1.0/After 1.0 with updated priorities.
Core API and versioning documentation docs/index.md, docs/protocol/versioning.md	Declares Rezi as beta with stable documented core API, breaking changes batched and documented in changelog with migration notes, references widget stability page for per-widget guarantees.
Constraint and layout guide updates docs/design-principles.md, docs/guide/constraints.md, docs/guide/constraint-recipes.md, docs/guide/debugging-constraints.md, docs/guide/layout-decision-tree.md, docs/guide/layout.md, docs/reference/constraint-expressions.md	Updates constraint documentation to reflect beta-line contract: helper-first API is canonical, grid.columns accepts `number
Widget stability tier documentation docs/widgets/index.md, docs/widgets/stability.md	Updates stability tier descriptions to reference current beta line instead of pre-alpha, clarifying that stable tier is the strongest pre-1.0 contract while the package remains in beta.

JSX Factory-Component Parity Test

Layer / File(s)	Summary
JSX component factory parity assertions packages/jsx/src/__tests__/uiParity.test.ts	New test suite deriving ui.* factory and JSX component name sets from @rezi-ui/core and the local layer, asserting bidirectional consistency (with explicit UI-only and JSX-only exclusions) and verifying package re-exports.
