improve agent CI matrix, token permissions, and waitlist follower backfill (#313)

* add workflows permission to git token and waitlist improvements

- add `workflows` to `InstallationTokenPermissions` type in both action and API token routes
- include `workflows: write` in the git token so agents can push workflow file changes
- add `githubFollowers` field to WaitlistSignup schema with migration
- add script to populate waitlist followers from GitHub API
- add frog-green-square-border logo asset

* improve CI, agent logging, token permissions, and delegation guardrails

- add format check and build step to root CI job
- standardize agent model/effort log lines across all agents
- fix GitHub App permissions types to match OpenAPI schema (workflows is write-only)
- improve delegation error message to prevent subagent recursion
- demote noisy OpenCode stderr to debug level
- add subagent delegation rules to resolved instructions

* remove module-level env var throws that break CI build

* fix logging bug and type hole from PR review

- use batch-local notFound counter so per-batch log doesn't undercount
- add workflows to WorkflowTokenPermissions so wire type matches what action sends

* drop pnpm build from CI test workflow

* fix delegate-effort test regex to match actual log format, disable fail-fast for agnostic tests

the test was matching `running \w+ with effort=auto` but the actual log
line from shared.ts is `» effort:  auto`. also temporarily set
fail-fast: false on action-agnostic so all failures surface at once.

* disable fail-fast in action workflow too, relax ci.test.ts to match

both workflow files now use fail-fast: false for agnostic tests so all
matrix jobs run to completion. the ci consistency test now checks that
the two workflows agree rather than requiring true.

* restore fail-fast: true now that all agnostic tests pass

* skip agent tests in CI when agent harness file didn't change

adds action/test/changed-agents.sh which reads the PR diff (via
dorny/paths-filter) and outputs only agents whose harness file was
modified. the action-agents matrix now uses this dynamic list instead
of a hardcoded array, so e.g. a PR touching only cursor.ts runs 6
jobs instead of 30.

* update ci.test.ts to validate dynamic agent matrix

the test now checks that the matrix references the changes job output
and that changed-agents.sh correctly discovers all agents.

* parallelize action jobs and use claude canary fallback for shared changes

runs action-agents in parallel with action-agnostic after root/changes, and updates changed-agents logic so shared or non-harness action runtime changes run only claude while harness-specific edits run only those changed agents.
