feat(metadata): add SURVEY ServiceDomain

[samkujovich]

Summary

Adds a SURVEY value to the ServiceDomain enum in arcade_core.metadata.

Survey / form / questionnaire builders (Google Forms, Typeform, SurveyMonkey, Qualtrics, etc.) have no fitting ServiceDomain today — none of the existing values passes the 10/10 test for "is this a survey tool?". Per the tool-metadata convention, a missing-but-warranted category should be added upstream (the same path OBSERVABILITY took for Datadog) rather than forcing tools into the wrong domain or defaulting to None.

SURVEY = "survey"
"""Survey, form, and questionnaire builders for collecting and analyzing responses."""

First consumer

The Google Forms worker toolkit (ArcadeAI/monorepo#939). Its 21 tools currently ship without a Classification because no domain fit; once this releases, that toolkit will bump its arcade-mcp-server minimum and classify all tools as SURVEY.

Test plan

• Adds test_decorator_accepts_survey_domain mirroring the existing per-domain acceptance tests.
• New enum member only; no behavior change to existing domains.

Note

Low Risk
Additive enum member and version bump only; no changes to validation logic or existing ServiceDomain values.

Overview
Adds ServiceDomain.SURVEY ("survey") to arcade_core.metadata so survey, form, and questionnaire integrations (e.g. Google Forms) can be classified for discovery and search boosting instead of leaving Classification unset or mis-tagging another domain.

arcade-core is bumped 4.9.0 → 4.10.0 for the release. A decorator acceptance test test_decorator_accepts_survey_domain follows the same pattern as other per-domain tests; existing domains and validation rules are unchanged.
