[2.x] Regenerate the node types from the v2 spec

[lorisleiva]

This PR repoints @codama-internal/spec-generators at @codama/spec@2.0.0-rc.0 and regenerates @codama/node-types, @codama/nodes and @codama/visitors-core against the v2 spec. The hand-written packages are adapted to the v2 shapes in the follow-up PRs, so they remain red until those land.

Generator changes

• Single-major generator. Drops the @codama/spec-v1 alias and the frozen v1 generation step. The v1 node types in @codama/upgrade are now a frozen static snapshot (packages/upgrade/src/v1/README.md); the generator only renders the spec on its own branch, and prior majors are ported forward by patch.
• Base attributes. Appends spec.base (the universal plugins) to every node, so plugins is a TPlugins type parameter on every interface and constructor and is visited by the identity/merge visitors. textNode gains plugins too.
• docs === text. Both render as string | TextNode and are visited (guarding the string-or-textNode duality). Deletes the v1 Docs alias and the parseDocs/DocsInput array layer.
• Identifier casing preserved. Constructors brand identifiers via identifierString rather than re-casing them, per v2 dropping the camelCase mandate.
• CODAMA_VERSION names the spec shape. Pre-release metadata is stripped (2.0.0-rc.0 → 2.0.0); the CodamaVersion type stays strict.
• Constructor ergonomics. Trailing optional positional parameters fold into the options bag (e.g. constantNode(identifier, type, value, { docs })); pluginNode(namespace, payload?, { plugins }) keeps its payload positional.
• Branded-string validation. Factories accept plain string for identifier/namespace/path/integer/decimal attributes and validate them through identifierString/namespaceString/pathString/integerString/decimalString, which throw CODAMA_ERROR__INVALID_BRANDED_STRING on a malformed value.
• Dead meta-model removed. Nested-union / tuple / float handling deleted.

Verification

Generated output type-checks, lints and is idempotent; the frozen v1 snapshot is untouched. The v2 changes are documented in a single major changeset alongside the seeded one from the cut.
