Lab #621: Add a way to list registered report definitions (report search only lists results)

Problem

swamp report search [query] lists stored report results (artifacts from past runs), not the report definitions currently registered/loaded from extensions/reports/. After authoring a new report (for example a workflow-scope report), there is no direct command to confirm it loaded and is selectable before running anything — report search returns an empty result set until the report has executed at least once and produced a stored artifact.

Steps to reproduce

Add a new report under extensions/reports/ (e.g. a workflow-scope report with a fresh name).
swamp report search <name> --json -> { "issues"/"results": [] } because the report has never run, even though it is correctly registered (it does run and produce output once the workflow executes).
There is no swamp report list / --definitions equivalent. swamp doctor extensions confirms extensions load but does not enumerate report definitions, and swamp model get <model> --json shows the resolved report set only for reports attached to a specific model.

Proposed solution

Add a way to list registered report definitions — name, scope, and source file/extension — distinct from stored results. For example a swamp report list command, or a reports section in swamp doctor extensions --verbose. This lets authors verify a report registered before its first run.

Alternatives considered

Run the workflow/method once, then swamp report search — but that conflates "is it registered" with "has it produced output", and gives no signal if the report failed to load.

Environment

swamp 20260608.234005.0-sha.ed5f78a4.

extension push: issue-verdict review is indistinguishable from missing/stale

Document model-method data-mutation surface (dataRepository.delete, findAllForModelSince, queryData)

@swamp/aws/cloudformation: expose StackSet instances, drift, and operations (Cloud Control cannot)

extension push: adversarial-review report hash is platform-dependent (macOS vs Linux), so committed reviews never match a cross-OS runner

model search --json returns a bare model object instead of {query, results} when exactly one model matches

model delete --json output shape doesn't match the documented {deleted, modelId, modelName, artifactsDeleted}

Extension API: allow export const extension to add resource specs, or document that it cannot

workflow validate: method args with a Zod .default() are treated as required

extension quality scorer mis-detects quoted phrases in comments as bare imports

Support CI-friendly adversarial review artifacts for extension push

extension push --dry-run --json reports local helper imports as bogus model entries

Extension source: direct-content export scan only reads first 64 KiB, silently drops exports beyond it

Managed skills ship with dangling reference-doc links

Add a list/discover method to dbcluster for enumerating clusters in a region

workflow-scope report's dataRepository.getContent returns null for data written in the same workflow run

dbcluster state schema is missing DBClusterMembers (writer/reader, instance class)

workflow direct-execution inputs.* persist as globalArguments on auto-definitions and freeze on first run

Workflow validation should resolve modelType for direct-execution steps

bucket-policy StateSchema.PolicyDocument declared z.string() but CloudControl returns it as a parsed object

bucket-policy GlobalArgsSchema requires Bucket and PolicyDocument, blocking workflow-YAML direct execution of get

Report execute throws are advisory: workflow marked succeeded, exit 0, AND report output is discarded

dataRepository.getContent rejects string type in production but docs and testing helper demonstrate strings
