Oleg Isonen 8e7a8a21aa feat: Report anonymous MCP reliability issues (#6021)
Closes #6020

## Summary

Adds the first end-to-end slice for anonymous, LLM-authored reliability
reports from the CLI and MCP.

The shared report contract captures the generalized user story,
attempted workflow, expectation, actual result, recovery attempts, user
impact, technical context, acceptance criteria, and agent runtime
(client, provider, model, version, and reasoning effort). Guidance
requires removing any user- or project-identifying information before
submission.

## Architecture

- Adds a project-authenticated `api.reports.issue` tRPC mutation as the
reusable product boundary.
- Maps that mutation to the public `report-issue` operation for CLI and
MCP callers.
- Keeps the endpoint directly callable from a future Builder UI through
the existing tRPC client.
- Publishes through a server-side GitHub App installation, so end users
do not need GitHub accounts or tokens.
- Discovers the App installation for the fixed Webstudio reporting
repository instead of requiring deployment-specific installation or
repository configuration.
- Searches for a hidden anonymous technical marker before creation to
avoid obvious duplicates.

## Todo

1. [x] Define a shared anonymous LLM-authored report contract.
2. [x] Include the user story, attempted workflow, expected and actual
behavior, recovery attempts, impact, technical context, and acceptance
criteria.
3. [x] Include the LLM client, provider, model, client version when
known, and reasoning effort.
4. [x] Attach sanitized CLI, Node.js, operating-system, architecture,
execution-mode, and API-contract metadata automatically.
5. [x] Add the Builder-reusable project tRPC mutation.
6. [x] Expose the mutation to CLI and MCP as `report-issue`.
7. [x] Add GitHub App authentication and issue publication.
8. [x] Reduce deployment configuration to the App ID and private key.
9. [x] Add marker-based duplicate detection.
10. [x] Add guidance for explicit user-requested reports and qualifying
repeated-friction reports.
11. [x] Review and simplify repeated GitHub request handling and public
protocol exports.
12. [ ] Add server-side throttling and harden concurrent duplicate
creation.
13. [x] Configure and install the reporting GitHub App in deployed
environments.
14. [x] Exercise the deployed endpoint with a controlled test report.
15. [ ] Run the complete agent evaluation suite after explicit approval.
16. [x] Review documentation impact and update the generated MCP
documentation.

## Verification

- Protocol issue-report contract tests: passed (3)
- Builder GitHub reporting tests: passed (4)
- Builder API router tests: passed (30)
- CLI schema, command-doc, MCP, and project-session tests: passed
- Protocol, HTTP client, project-build, CLI, and Builder typechecks:
passed
- Root lint: passed
- Generated API and documentation checks: passed
- New and changed regression tests were demonstrated failing against the
previous behavior, then passing after implementation
- No fixture inputs or outputs are affected
- Agent evaluations were not run because they require explicit approval

## Deployment notes

The Builder only needs `GITHUB_ISSUE_REPORT_APP_ID` and
`GITHUB_ISSUE_REPORT_PRIVATE_KEY`. The server discovers the App
installation for `webstudio-is/webstudio` and creates a short-lived
installation token. The App needs repository metadata read access and
Issues write access.

## Known limitations

Duplicate detection currently uses GitHub issue search and can race when
identical reports arrive concurrently. The endpoint is
project-authenticated, but dedicated server-side throttling remains a
follow-up before production rollout. No Builder UI is included yet; the
tRPC boundary is intentionally ready for one.

Protocol

@webstudio-is/protocol owns Webstudio data exchange protocols.

The project bundle is the external export/import artifact used by sync, local .webstudio/data.json, project import, transferred asset files, and prebuild. This package owns the assembled bundle schemas, transfer RPC payloads, and bundle compatibility/version helpers.

Domain models such as pages, assets, and serialized builds remain owned by their domain packages and are composed here through schema-only entrypoints. Do not copy those schemas into this package.

Terminology

Project bundle is the authoritative external project artifact. It is used by sync, .webstudio/data.json, project import, transferred asset files, and prebuild.

Data envelope is a serialized single-key object whose key is a versioned Webstudio marker, for example { "@webstudio/instance/v0.1": data }. The envelope identifies the payload version and lets consumers detect malformed Webstudio-owned data before falling back to other formats.

Transfer data is the domain payload inside a data envelope. Examples include InstanceTransferData, InstancesTransferData, and PageTransferData. Transfer data is portable and detached from a project; insertion/import remaps ids and merges it into authoritative project state. Runtime-owned transfer formats live in @webstudio-is/project-build/transfer.

Clipboard data is a UI transport concern. Builder copy/paste may serialize transfer data into a data envelope and place it on the browser clipboard, but runtime and protocol code should name the reusable format as data envelope or transfer data, not clipboard.
