Nicky LeachandPaperclip 24bbc0f57e docs: add telemetry marker workflow (#9543)
## Thinking Path

> - Paperclip is an open-source agentic AI management platform that
ships anonymous usage telemetry to understand product health and
adoption.
> - The telemetry system has a generated contract
(`packages/shared/src/telemetry/generated/paperclip-telemetry.ts`) that
types every first-party event the product emits.
> - When a product change needs a new first-party event that is not yet
in the generated contract, contributors had no public workflow
explaining how to propose an event or later promote it into the contract
once accepted.
> - The gap leads to confusion at call sites: contributors either skip
tracking entirely or emit untyped events that bypass the privacy and
governance safeguards built into the contract.
> - This PR fills that gap by adding `doc/TELEMETRY_WORKFLOW.md` — a
public contributor guide that covers the full propose → promote
lifecycle: the `@ts-expect-error -- proposed-telemetry(...)` marker, the
canonical multi-line `track()` shape, the TS2578 expiry signal, and the
look-up-by-event-name promotion step.
> - `packages/shared/src/telemetry/README.md` gains a cross-reference so
readers of the data-contract doc can find the workflow guide without
searching.
> - `README.md` gains a one-line pointer in the telemetry section so the
workflow is discoverable from the project entry point.

## Linked Issues or Issue Description

No pre-existing public GitHub issue covers this doc gap. Inline
description:

**Problem:** Contributors adding product telemetry for events not yet in
the generated contract have no documented workflow. The
`@ts-expect-error -- proposed-telemetry(...)` pattern exists in the
codebase but is undocumented, leading to inconsistent usage and missing
adoption signals.

**Solution:** A new public guide (`doc/TELEMETRY_WORKFLOW.md`) documents
the marker format, the recommended multi-line `track()` shape that
preserves the TS2578 expiry signal, the dimension rules, and the
promotion checklist. Cross-references are added to
`packages/shared/src/telemetry/README.md` and the top-level `README.md`.

## What Changed

- **New file `doc/TELEMETRY_WORKFLOW.md`** — public contributor guide
for the propose/promote lifecycle: marker format, canonical multi-line
example, TS2578 single-line trap, dimension rules, and step-by-step
promotion checklist.
- **`packages/shared/src/telemetry/README.md`** — added one-line
cross-reference pointing at `doc/TELEMETRY_WORKFLOW.md` for proposed
events not yet in the generated contract.
- **`README.md`** — added one-line pointer in the telemetry section so
the new workflow guide is reachable from the top-level project entry.

## Verification

This is a docs-only change. Verification steps:

1. Open `doc/TELEMETRY_WORKFLOW.md` and confirm it contains:
   - The `^[a-z0-9][a-z0-9._:-]{1,63}$` event-name grammar.
- The exact `// @ts-expect-error -- proposed-telemetry(<issue>):
<rationale>` marker.
- The multi-line `client.track()` copy-paste example (directive on line
before event-name string).
- The explanation of the TS2578 single-line trap and the
look-up-by-event-name step.
   - The promotion checklist in the "Promote An Event" section.
2. Confirm `packages/shared/src/telemetry/README.md` cross-references
`doc/TELEMETRY_WORKFLOW.md`.
3. Confirm the `README.md` telemetry section links to
`doc/TELEMETRY_WORKFLOW.md`.

## Risks

Low risk — docs-only change. No runtime behavior, schema, or existing
telemetry emission is affected. The risk is that the guidance could
diverge from the actual enforcement in the codebase over time; mitigated
by linking to the generated contract and keeping the doc in the same
repo.
