Changelogs and variants map: C2a's entries sit under Unreleased, not 0.15.0

The manifests stay at main's versions; C2a's bumps are not releases (c0-ships-with-c2a).

 - **Inputs.** The bytes at the path. **Outputs.** The decoded store with header and catalog; or a typed refusal (`CultStoreUnreadableException` in C#; `CultCacheStoreUnreadable{path, kind}` in Rust, kind `Undecodable` or `UnsupportedFormat`; `StoreUnreadableError` in TS and Python). A refusal names a header only as `cultcache.store.v<digits>`.
 - **Derived state.** The write header is never decided by the writer: it is the reader's verdict (header read, whole-store flag, whether ids or variants are held). A rewrite of a file that cannot be read cannot happen, because the reader throws first.
 - **Forbidden writers.** A second header classifier. Deleted: Rust `leading_header`, `read_array_header`, `read_string`; cultnet-ts's own decode of the store header; the TS async `readStore`; Rust `StoreUnreadableError` (negative grep `StoreUnreadableError` in `packages/cultcache-rs`: no match); Python `_decode_v1_snapshot`.
-- **Shared paths.** cultnet-ts reaches the header decision only through `readSingleFileStore` (AUTH:4, :321) and checks only record count, schema id and type. cultnet-ts therefore declares cultcache-ts `^0.15.0`, the first release that exports it.
+- **Shared paths.** cultnet-ts reaches the header decision only through `readSingleFileStore` (AUTH:4, :321) and checks only record count, schema id and type. cultnet-ts therefore needs a cultcache-ts release that exports it, which is the release that ships with this change; the manifests move to that version then (c0-ships-with-c2a), not before.
 - **Cut line.** `merge-r1` h3 (Rust) and h4 (TS, cultnet-ts); spec `cut-merge-r1.r3` authority map.
 - **Pinned by.** `tests/vectors/document-variants-c2a/readability/manifest.txt`, walked by `StoreReadabilityTests.OpenReadsExactlyTheFilesTheVectorsSayItReads` (C#), `CultMeshSingleFileReadabilityTests.AWriteReplacesAFileExactlyWhenItReads` (Mesh), `a_file_is_replaced_exactly_when_it_reads` (RS:5132), "SingleFileMessagePackBackingStore replaces a file exactly when it reads" (TS test :2321) and `test_single_file_replaces_a_file_exactly_when_it_reads` (Python). AUTH cases: `packages/cultnet-ts/test/idunn-runtime-authority.test.ts`. Declared divergences in the manifest: `legacy-envelopes.bin` (C# refuses; the others read and replace it) and `variant-slot-v3.bin` (C# reads; the others refuse).
 - **Known gaps.** `variants:follow_up:c0-bad-canonical-in-manifest` (`current-catalog-bad-canonical.msgpack` is not in the manifest; TS reads it, Rust refuses). `variants:follow_up:legacy-vectors-all-runtimes` (the three `legacy-catalog-*` c0 vectors have a verdict only in C# tests; all four runtimes refuse them, probed). `variants:follow_up:range-check-in-ci` (`npm run test:pack:ts` builds every admitted tag and checks exports, but `.github/workflows/publish-packages.yml` does not run it).
