ci: Configure SDK compliance capture suite

[marandaneto]

Problem

SDK compliance workflows need explicit harness suite/sdk-type selection and configurable blocking behavior so CI only runs the intended contract checks.

Changes

• Point SDK compliance to the harness branch with new workflow inputs.
• Run capture v0 as a server SDK.
• Keep compliance failures non-blocking for now.
• Align local compose with the same suite/sdk type.

Testing

• Parsed workflow YAML.
• Ran docker compose config for the adapter compose file.
• Ran git diff --check.

Release / changeset

No SDK package changeset: CI/local compliance configuration only.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Implemented with Pi using dedicated git worktrees. The change was requested to align SDK compliance harness setup across SDK repositories while keeping non-ready SDKs non-blocking.

Mutable branch reference in reusable workflow call

The uses line was changed from a pinned commit SHA to a branch name (fix/sdk-harness-options-20260630). Branch references are mutable: any push to that branch in the external posthog-sdk-test-harness repo will immediately affect what code runs inside this workflow, including in a security context with access to secrets. If the branch is ever force-pushed or receives an unreviewed commit, CI will silently pick it up. This also makes the build non-reproducible — the same workflow run could behave differently on different days.

Once the harness branch is merged, this should be updated to either the merge commit SHA or the next tagged release SHA.
