manifests: fields missing from `Manifest` compared to the app manifest reference

[yuya-takeyama]

Description

Compared with the app manifest reference, the following keys have no corresponding field in Manifest (manifests.go, master 4b9cec9 / v0.29.0). Because ExportManifestContext decodes into Manifest and UpdateManifestContext sends it back, these keys are not carried through an export → update round trip.

features

Key	Type in the reference
features.agent_view	object: agent_description (required, max 300 chars), suggested_prompts[]{title, message}, actions[]{name, description}
features.assistant_view	object: assistant_description (required), suggested_prompts[]{title, message}
features.rich_previews	object: is_active bool, entity_types []string
features.search	object: search_function_callback_id (required), search_filters_function_callback_id, slackbot_metadata{description, examples[], example_query}
features.unfurl_domains	[]string (max 5)

oauth_config

Key	Type in the reference
oauth_config.pkce_enabled	bool
oauth_config.token_management_enabled	bool

settings

Key	Type in the reference
settings.event_subscriptions.metadata_subscriptions	[]{app_id, event_type}
settings.incoming_webhooks	object: incoming_webhooks_enabled bool
settings.token_rotation_enabled	bool
settings.is_hosted	bool
settings.is_mcp_enabled	bool
settings.siws_links	object: initiate_uri string
settings.function_runtime	string (remote / slack)

Top level

Key	Type in the reference
app_directory	object (Slack Marketplace listing fields)
functions	map keyed by callback_id (input_parameters / output_parameters differ between manifest v1 and v2)
workflows	map keyed by callback_id
datastores	object
outgoing_domains	[]string (max 10)
types	object (max 50)
metadata_events	object or reference form
external_auth_providers	object (CUSTOM / SLACK_PROVIDED)
compliance	object: fedramp_authorization, dod_srg_ilx, itar_compliant
mcp_servers	map keyed by server key (max 20)

For reference, Slack's own Go types for the manifest are in the Slack CLI (slackapi/slack-cli, internal/shared/types/app_manifest.go), and the Node SDK types are in slackapi/node-slack-sdk, packages/web-api/src/types/request/manifest.ts.

I plan to send a PR for features.agent_view and features.assistant_view.
