chore: changelog, exclude list, wasm support, slim tokio features

- Add CHANGELOG.md (Keep a Changelog format) covering 0.1.1 and 0.1.0
- Exclude AGENTS.md from the published crate (docs/reviews/ and
  docs/sdd_process.md were already excluded)
- Slim tokio features: full → rt, sync, time, io-util, macros (no
  net/fs/process usage in the crate)
- Enable wasm32-unknown-unknown: uuid rng-getrandom + getrandom 0.4
  wasm_js so request-ID generation works on wasm
- Add wasm + semver-checks to AGENTS.md pre-release verification

Verification:
- cargo test: 543 passed, 0 failed
- cargo clippy --all-targets -- -D warnings: clean
- cargo fmt --check: clean
- cargo doc --no-deps: clean
- cargo check --target wasm32-unknown-unknown: clean
- cargo clippy --target wasm32-unknown-unknown -- -D warnings: clean
- cargo semver-checks check-release: 196 pass, no semver update required
- cargo publish --dry-run --allow-dirty: succeeds (103 files, 1.8MiB)

+# Changelog
+
+All notable changes to this crate are documented here. The format is
+based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and
+this crate adheres to [Semantic Versioning](https://semver.org/).
+
+## [0.1.1] - 2026-08-17
+
+A minor release that renames the ALPN prefix from `alknet/` to `alk/`
+and drops the `alktype` dependency. No public API changes — verified
+with `cargo semver-checks` (196 checks pass, no semver update
+required).
+
+### Changed
+
+- **ALPN prefix renamed.** All ALPN strings changed from
+  `alknet/<name>` to `alk/<name>`: `alknet/call` → `alk/call`,
+  `alknet/channels` → `alk/channels`. The rename landed before the
+  first published consumer (alktty), so no interop break exists.
+  `CHANNELS_ALPN` is now `b"alk/channels"`; `CallAdapter::alpn()`
+  returns `b"alk/call"`; `derive_alpn_from_op_name` derives
+  `alk/<alpn>` from `channels/<alpn>/(sub|pub)` op names. ADR-004
+  amended with the rename rationale. See Review 003.
+- **`alktype` dependency dropped.** The only usage
+  (`alktype::validation::build_validator`) was a thin wrapper over
+  `jsonschema::options().build()`; the call site now uses `jsonschema`
+  directly. The crate is leaner — no `alktype` (and no transitive
+  `indexmap`/`hashbrown 0.17`) in the dependency tree.
+- **`tokio` features slimmed.** `features = ["full"]` replaced with
+  `["rt", "sync", "time", "io-util", "macros"]` — the crate uses no
+  net/fs/process features. This unblocks `wasm32-unknown-unknown`.
+- **WASM support.** The crate now compiles for
+  `wasm32-unknown-unknown` (verified with `cargo check` and `cargo
+  clippy` on the wasm target). `uuid` gained the `rng-getrandom`
+  feature and `getrandom 0.4` the `wasm_js` feature so request-ID
+  generation works on wasm.
+
+### Added
+
+- **BAST document for the chunk header.**
+  `docs/architecture/chunk-header.bast.json` is the machine-readable
+  wire-format spec for the channels 8-byte chunk header
+  (`[channel_id: u32 BE][length: u32 BE]`). BAST is plain JSON —
+  consumable by any language; the `alktype` crate compiles it into
+  readers/writers/validators, and future codegen derives
+  language-specific implementations. Embedded in the crate as
+  `channels::wire::CHUNK_HEADER_BAST` so downstream Rust crates can
+  consume it without a file lookup. The hand-rolled
+  `parse_header`/`write_header` functions remain the hot path; the
+  BAST document is the contract.
+
+## [0.1.0] - 2026-08-14
+
+Initial crates.io release. The unification of `alknet-call` (structured
+JSON RPC: operations, streaming subscriptions, service discovery) and
+`alknet-channels` (multiplexing proxy: N logical channels over one
+transport stream, channel 0 pre-negotiated as the call protocol).
+Vendored core types (`Connection`, `ProtocolHandler`, `BiStream`,
+`BidiStreamSource`, `AuthContext`, `IdentityProvider`, `Capabilities`,
+`OwnershipProvider`), the `Pub` operation type / `HandlerKind::Sink`
+(ADR-046), the channels protocol with openable-ALPNs-as-operations
+(ADR-047), and the `ChannelClient` transport-agnostic client.
