feat: introduce client event system (#106)
* chore(flake): accept extra system attr; add perl for openssl-sys build

forAllSystems calls the lambda with {system, pkgs}; strict
destructuring requires `..` to ignore the system attribute.

`pkgs.perl` is needed because openssl-sys is pulled vendored via
libsqlite3-sys / rusqlite / chat-sqlite, and its `perl Configure`
step needs FindBin.pm, which Fedora's system perl doesn't ship.

* feat: introduce client event system

- Core processing yields a `PayloadOutcome` enum — `Empty`, `Convo`, or
  `Inbox`. `ConvoOutcome` carries a conversation id and an optional
  decrypted `Content`; `InboxOutcome` adds a `NewConversation`
  (id + `ConversationClass`) for a peer-initiated conversation.
- Client translates `PayloadOutcome` into app-facing `Vec<Event>`
  (`ConversationStarted`, `MessageReceived`) at the boundary, so the
  application loop sees discrete events rather than core types.
- MLS group welcomes produce a `ConversationStarted` event with no
  initial content, fixing the silent-group-join case where the inbox
  layer dropped the observation.
- C FFI exposes an `EventList` opaque type with indexed accessors and
  an `Invalid` sentinel for out-of-bounds / non-applicable reads.
- Symmetric `Inbox` / `InboxV2` handlers: both return
  `Result<InboxOutcome, _>` and own the persistence + ephemeral-key
  cleanup for the conversations they create.
- Updated and simplified `docs/adr/0001-client-event-system.md`.

* chore(flake): bump nixpkgs to nixos-unstable-small

Temporary. The two crates.io UA fixes (NixOS/nixpkgs#512735 for
fetchCargoVendor's python-requests UA, NixOS/nixpkgs#524985 for
importCargoLock's curl UA) haven't propagated to nixos-unstable yet.
Switch to nixos-unstable-small and force logos-delivery to follow so
the smoketest gets the same fix. Revert once nixos-unstable catches up.

feat: implement Client crate and C FFI bindings (#73)
Implement a `client` crate that wraps the `libchat` context behind a
simple `ChatClient<D>` API. The delivery strategy is pluggable via a
`DeliveryService` trait, with two implementations provided:

- `InProcessDelivery` — shared `MessageBus` for single-process tests
- `CDelivery` — C function-pointer callback for the FFI layer

Add a `client-ffi` crate that exposes the client as a C API via
`safer-ffi`. A `generate-headers` binary produces the companion C
header.

Include two runnable examples:
- `examples/in-process` — Alice/Bob exchange using in-process delivery
- `examples/c-ffi` — same exchange written entirely in C; smoketested
under valgrind (to catch memory leaks) in CI

iterates: #71
