Clients that show follower counts for a list of accounts or entities have to call a list endpoint once per subject to read its totalCount.
Fix
Add app.certified.graph.getFollowerCounts: takes up to 100 subjects (account DIDs or entity AT-URIs) and returns one count per subject in input order. Entity URIs use the same shared validator as getEntityFollows, and counts use the same counting rules as listActorFollowers / listEntityFollowers.
Regenerate the client, docs explorer snapshots and skill references; add a changeset.

Summary
Adds app.certified.graph.getFollowerCounts for mixed batches of account DIDs and entity AT-URIs.
Clients can fetch follower counts for mixed account and entity lists.

Added a follower-count query that retrieves counts for up to 100 account or entity subjects in one request. Results follow the requested order, preserve duplicates, and return zero when no indexed followers are found.
Documented the new query and its request limits, response format, and errors.
Tests
Added coverage for mixed subject batches, result ordering, counts, invalid subjects, and query failures.
Adds app.certified.graph.getFollowerCounts for batched follower counts across account DIDs and entity AT-URIs. The query validates subjects, counts distinct publishers, and returns one result per input occurrence in request order.

Summary
Define the query contract and types happyview-modules/lexicons/*, packages/api/src/lexicons/app/certified/graph/*, docs/openapi.json, docs/sources/lexicons/*, .agents/skills/hypercerts-api/references/*, happyview-modules/README.md
Defines the query inputs, output, errors, API types, and OpenAPI documentation. The query accepts 1–100 mixed subjects and preserves input order and duplicates.
Validate subjects and query counts happyview-modules/lua/endpoints/getFollowerCounts.lua, happyview-modules/lua/src/getFollowerCounts.lua
Validates subjects and request limits, then queries distinct publishers in the account-follow and entity-follow collections. Results include zero for subjects with no matching rows.
Register the endpoint and release metadata happyview-modules/manifest.json, happyview-modules/modules/follower-counts/manifest.json, docs/sources/index.json, docs/coverage.json, .changeset/batch-follower-counts.md
Registers the Lexicon, module, and query script. Updates endpoint indexes and coverage totals, and adds minor release entries for both packages.
Verify and document batch behavior happyview-modules/tests/unit/tooling/*follower-counts*, happyview-modules/tests/unit/tooling/actor-follow.test.js, happyview-modules/tests/http/follower-counts.http.test.js, CONTRIBUTING.md
Adds unit and HTTP tests for mixed batches, duplicate inputs, ordering, zero counts, validation, query failures, and agreement with follower-list totals.

Resolve getEntityFollows conflict by taking main's shared subjectRecordUri validator; getFollowerCounts now uses it and the duplicate entityFollowTarget.lua is removed.
