Modernize SDK: plain structs + add missing API resources (cron, service connections, integrations, email)

[rusenask]

Brings the Go SDK up to date with the current REST API, in two parts.

Part 1 — drop protobuf, use plain structs

Removed the generated api/reactor/v1 package (the SDK's only protobuf dependency) and replaced the type aliases with plain structs mirroring the backend structs package. Also: go 1.23, io/ioutil → io, removed the dead proto Makefile target.

• Function.Id → Function.ID; Variable now uses created_at/updated_at (time.Time) and drops configuration_ids; Request/Response gain metadata/body_path/modified_body_path.

Part 2 — add missing resources + sync drifted fields

New resources (structs mirror the backend structs package):

File	Resource	API
crons.go	Cron + CRUD	/v1/crons
service_connections.go	ServiceConnection (GCP/AWS/Azure) + CRUD	/v1/service-connections
service_connection_inputs.go	ServiceConnectionInput incl. email-to-webhook (EmailInput)	/v1/buckets/{id}/service-connection-inputs
service_connection_outputs.go	ServiceConnectionOutput incl. Discord/Slack	/v1/buckets/{id}/service-connection-outputs
integrations.go	IntegrationConfiguration (notifications) + CRUD + add/remove bucket	/v1/integrations

Note: "email webhooks" is a service-connection input of type email (no separate resource). The internal /v1/email-inbound endpoint is server-to-server and intentionally not in the SDK.

Synced fields that had drifted on existing resources:

• Output: cron_id, response_function_id, retries, tls_verification, rules (full rule tree), created_by, durability (DurabilityConfig), throttle (ThrottleConfig)
• Bucket: static_ip, account_id, cron_id, service_connection_inputs/outputs, integration_configurations; BucketAuth gains id/created_at/updated_at
• Input: strip_path_prefix, tls_version, legacy_tls, created_by
• Tunnel: agent_id; Features gains skip_insecure_verify

Breaking changes

Function.Id→Function.ID and the Variable reshape (Part 1). Warrants a minor version bump on the next tag.

Verification

go build ./... ✓ · go vet ./... ✓ · new network-free JSON round-trip unit tests pass (unix-int timestamps on integrations, omitempty pointer sub-configs, time.Duration on durability/throttle, rule tree). Pre-existing integration tests still require a live RELAY_KEY.

Note

Medium Risk
Breaking type/auth changes for consumers plus a large API model expansion; behavior changes (force delete, config list parsing) need a minor version bump and careful rollout.

Overview
This PR brings the Go SDK in line with the current REST API: protobuf is removed (generated api/reactor/v1 deleted) and reactor/function types are plain JSON structs with breaking renames (Function.Id → ID, reshaped Variable timestamps/fields).

Authentication adds NewWithAPIKey (Bearer RELAY_API_KEY), documented in the README; CI and integration tests prefer it over key/secret Basic auth.

New API surface: crons, service connections, service-connection inputs/outputs (including email and Discord/Slack), and integration (notification) configs. Existing models gain fields such as bucket static_ip / nested connections, output durability/throttle/rules, and input TLS options. DeleteBucket now supports ?force=true when inputs/outputs remain.

Tests shift to smoke + httptest unit coverage and a live integration lifecycle; the Makefile drops the dead proto target. Go 1.23 and fewer dependencies (golang/protobuf removed).

Integration create sends bogus timestamps

Medium Severity

IntegrationConfiguration.MarshalJSON always encodes created_at and updated_at from time.Time.Unix(), including when those fields are zero. CreateIntegration (and updates built from a fresh struct) therefore POST/PUT bodies with large negative unix timestamps instead of omitting read-only times, unlike the new Cron writer which omits them on create/update.
