chore: release package (beta)

[github-actions]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

main is currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, run changeset pre exit on main.

Releases

@adcp/sdk@9.0.0-beta.26

Minor Changes

• 6e09e6a: Add RegistryClient.upsertCommunityMirrorAdagents for keyed community-mirror publishes, while keeping createCommunityMirrorAdagents as the generator-only helper.
• 35c276b: Add operation-scoped webhook URL template filters and per-call webhook suppression, and capture build_creative variant context from storyboard responses.

Patch Changes

• e8d05ea: Repair local compliance bundles whose latest selector leaked into ComplianceIndex.adcp_version by deriving the
  real AdCP version from the matching schema bundle before storyboard execution.
• 8681d6e: Preserve storyboard create_media_buy sample requests that set start_time: "asap" instead of rewriting them to a generated future timestamp.
• a415b20: Avoid false-positive missing-valid-actions advisories when a later get_media_buys observation in the same compliance run includes valid_actions.

Approved release PR for 9.0.0-beta.26; includes the merged webhook/template and creative context changeset plus prior pending changesets.

Standard Changesets release PR — approving. Version bump is owned by the release action, not hand-edited, which is exactly the contract in CLAUDE.md.

Things I checked

• All four version touchpoints move in lockstep to 9.0.0-beta.26: package.json:3, packages/client-shim/package.json:108 dependency pin, and src/lib/version.ts both LIBRARY_VERSION (L7) and VERSION_INFO.library (L94).
• ADCP_VERSION / VERSION_INFO.adcp correctly stays pinned at 3.1.0-rc.9 — library version and schema version are independent and this PR only moves the former.
• No manual package.json version edit — the bump is the changesets action (PR body confirms), so MUST FIX #6 does not apply.
• CHANGELOG.md entries (two minor: community-mirror-create-upsert, webhook-scope-creative-context; three patch) match the five slugs added to .changeset/pre.json. Two minors → minor bump, which is what beta.25 → beta.26 reflects under pre mode.
• version.ts generatedAt advanced to the release timestamp — generated artifact, no logic change.

Safe to merge once CI is green.
