refactor(api): auto-inject discriminator value via generated MarshalJSON

Sealed-interface union variants now hardcode their wire discriminator
inside a generated MarshalJSON method instead of forcing callers to set
the field on every struct literal. Drops a class of silent-rejection
bugs where a typo in the discriminator slipped past the type checker
and through to Telegram, which then rejected the request with no
Go-side signal.

The discriminator field stays exported so incoming-message decoding,
type switches and debugging still see it. MarshalJSON wraps via a
function-local type alias and emits an outer field with the same json
tag; encoding/json (and goccy/go-json) resolve the outer field as the
shallower one and override whatever the caller wrote.

99 variants get MarshalJSON. 7 are skipped because their unions
dispatch structurally rather than by a string field: Message and
InaccessibleMessage (MaybeInaccessibleMessage, dispatched on date),
and the InputMessageContent family (InputTextMessageContent,
InputLocationMessageContent, InputVenueMessageContent,
InputContactMessageContent, InputInvoiceMessageContent — Telegram
identifies these by the presence of message_text / latitude /
phone_number / title etc.).

Discriminator extraction lives in the emitter (cmd/genapi/emitter.go).
Resolution: knownDiscriminators reverse-lookup for the 13 auto-decode
unions, then doc-string analysis ("must be X" / "always “X”")
of the variant's first required string field for marker-only unions
(BotCommandScope, InputMedia, InputPaidMedia, InputProfilePhoto,
InputStoryContent, InputPollMedia, InputPollOptionMedia,
InlineQueryResult, PassportElementError). Variants the emitter cannot
resolve a discriminator for are skipped silently rather than emitting
broken code.

Internal call-site cleanups: 4 manual discriminator assignments
removed (api/unionparam_test.go,
dispatch/filters/message/message_test.go, examples/inline/main.go ×2).
Regression tests added in api/marshaljson_variants_test.go covering
type-keyed variants, source-keyed variants, the override-user-typo
guarantee, round-trip preservation through UnmarshalChatMember, the
no-discriminator InputMessageContent path, and ride-along of
non-discriminator fields.

regen-from-fixture is deterministic across two consecutive runs;
go test -race / go vet / staticcheck all clean.

 ListenAndServe starts an HTTP server on addr and blocks until Stop is called \(which triggers Shutdown with the caller's context\) or the server returns an error other than http.ErrServerClosed. Callers must invoke Stop\(ctx\) to cleanly shut down the server; the ctx passed here is only used as the server's base context for incoming requests.

 Run implements Updater. It blocks until Stop is called or ctx is cancelled. If the server has not been started via ListenAndServe, Run only watches for shutdown — the user is expected to mount ServeHTTP on their own router.
