Nicky LeachandPaperclip 80a2b9284b Define durable runtime activity events (#18129)
## Thinking Path

> - Paperclip manages agents and tasks.
> - Runner reports durable run events through PRP.
> - Runtime clients need a typed record of reported activity.
> - The event must keep the normal run authority and read boundaries.
> - This pull request adds the generic runtime activity event contract.
> - Later PRs can publish and consume this contract without private
plugin coupling.

## Linked Issues or Issue Description

First feature prerequisite extracted from #18050. Runner publishing is
#18050; the dependent consumer is #18131. Related independent test
stability work: #18128. The parent search and review history is
preserved in [the verification
archive](https://github.com/paperclipai/paperclip/pull/18050#issuecomment-6489369676).

**Subsystem affected**

Runner event protocol, server run-event persistence and redaction, and
UI event taxonomy.

**Problem or motivation**

Core needs a durable, typed activity record tied to the authenticated
run. A text marker is not an event contract.

**Proposed solution**

Add `runtime.activity.recorded` as a P1 event with a closed `{
namespace, activityKey }` payload. Runner knows no plugin or panel
identity. Run/session identity, sequence and emission time stay in the
outer envelope; Core resolves company, task and agent through the
authorized run binding. Use the existing authenticated persistence,
acknowledgement, replay and redaction paths.

## What Changed

- Define and validate the event in PRP v1, v2 and v3. Update the
generated protocol artifacts and event catalog.
- Preserve saved and live event redaction. Test persistence, replay
deduplication and the existing run-read boundary.
- Register the event in the UI taxonomy without changing panel display
behavior.
- Advance the source-bound Copilot identity to 78. Retain all published
historical identity fixtures without changing their bytes.

## Verification

- Root `pnpm typecheck` and `pnpm build`: passed for the revised
activity contract.
- Node protocol checks: 14 passed. Provider identity and registry tests:
185 passed. Server tests: 103 passed. UI event registry: five passed.
- Maintained Grok and Copilot identity generator checks and `git diff
--check`: passed.
- The first activity-contract review scored 4/5 because the dependent
producer and readers still used the earlier contract. Both dependent PRs
are now updated and restacked; the finding is resolved and review is
running again.
- Initial extraction retained a consumer-only import in one server
suite. That suite failed to load. The consumer case and import were
moved out; the final three server files passed all 103 cases.
- Earlier panel-specific head `6137c50bc` had green CI and standard/Apex
5/5. Those scores do not qualify this revised activity contract. Fresh
CI and reviews are pending. Earlier combined results in the archive
apply only to their recorded source revisions.

## Risks

This change is additive. It adds no route, publisher, filesystem
transport, provider sandbox grant, or panel display behavior. Activation
hints grant no permission to read a plugin view. Provider identities
bind the changed protocol source; historical identities remain
decode-only. No schema migration or dependency change is required.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, repository tools and code
execution. The exact serving snapshot is not exposed.
