chore(release): stamp 0.2.0

Section the changelog, add the release notes with the Windows
verification disclosure, update the current-release stamps, and repoint
the release process from the retired GitHub commands to Codeberg.

+# PureYAML 0.2.0
+
+The parser is now a faithful pure-Swift port of libyaml's scanner and parser
+(`PureYAML.Parsing.LibYAML`), replacing the original hand-rolled engine
+entirely. The port was verified against libyaml built from source and then
+pushed past it: whole-suite conformance against the official YAML test suite
+is **402 of 402 cases, zero gaps** (`Tests/Fixtures/yaml-test-suite-manifest.yaml`
+is the machine-authoritative record), including six rejections libyaml itself
+gets wrong (QB6E, DK95/01, Y79Y/003, S98Z, ZXT5, DK4H). Canonical event
+conformance is 308 of 308 valid cases. Measured throughput is 1.6x to 2.15x
+faster than Yams on real-world documents.
+
+## Added
+
+- `PureYAMLJSON`, a second library product: a standalone YAML to JSON and
+  JSON to YAML converter with a strict JSON-representability validator
+  (unique string keys, finite numbers), built on the Check algebra.
+- Opt-in located parse: `PureYAML.parseLocated(_:)` and
+  `PureYAML.parseStreamLocated(_:)` return a `Model.LocatedValue` tree in
+  which every node carries its source span (1-based line and column), with
+  exact scalar end positions. The plain `Value` path is byte-identical to
+  before; a whole-suite test proves the located projection equals a plain
+  parse for every passing case.
+- Type-directed validation: the `Validation.Check` algebra with combinators
+  and rule-identity configuration replaces the legacy `Rule` type.
+  `BuiltinCheck.mappingKeysAreUnique` ships in core; the JSON checks live in
+  `PureYAMLJSON`.
+
+## Changed
+
+- Undefined tag handles, tab indentation, under-indented quoted-scalar
+  continuations, and the other strictness gaps are now parse errors, matching
+  the official suite's error cases. `PureYAML.validationReport(_:)` carries
+  such failures as parse diagnostics.
+- Diagnostics from the ported engine translate into
+  `PureYAML.Parsing.ParseError` with libyaml-style messages and 1-based
+  positions.
+
+## Verification
+
+- macOS: full gate (style, namespacing, forbidden patterns, changelog,
+  roadmap, swiftformat, swiftlint strict, debug and release build and test,
+  whole-suite conformance sweep).
+- Linux: debug and release build and test, Swift 6.3.2 on aarch64
+  (593 tests, 136 suites).
+- WASM: debug and release library builds with the swift-6.3.2-RELEASE_wasm
+  SDK.
+
+## Known deferred issues
+
+- Windows build and test were NOT run for this release: the Windows CI
+  workflow was hosted on GitHub and has no Codeberg runner equivalent yet.
+  The tree is pure Swift with no platform-conditional code paths added since
+  0.1.5, but Windows remains unverified until a runner exists.
+- The `docs/RELEASE.md` hosted-verification section still assumes the full
+  four-platform CI matrix; Codeberg Actions currently runs the
+  rules-conformance workflow only.
