Robin van Duiven 8d0c3d2fe6 fix(hermes): inject agent JWT into Hermes adapter env to fix identity attribution (#3608)
## Thinking Path

> - Paperclip orchestrates AI agents and records their actions through
auditable issue comments and API writes.
> - The local adapter registry is responsible for adapting each agent
runtime to Paperclip's server-side execution context.
> - The Hermes local adapter delegated directly to
`hermes-paperclip-adapter`, whose current execution context type
predates the server `authToken` field.
> - Without explicitly passing the run-scoped agent token and run id
into Hermes, Hermes could inherit a server or board-user
`PAPERCLIP_API_KEY` and lack a usable `PAPERCLIP_RUN_ID` for mutating
API calls.
> - That made Paperclip writes from Hermes agents risk appearing under
the wrong identity or without the correct run-scoped attribution.
> - This pull request wraps the Hermes execution call so Hermes receives
the agent run JWT as `PAPERCLIP_API_KEY` and the current execution id as
`PAPERCLIP_RUN_ID` while preserving explicit adapter configuration where
appropriate.
> - Follow-up review fixes preserve Hermes' built-in prompt when no
custom prompt template exists and document the intentional type cast.
> - The benefit is reliable agent attribution for the covered local
Hermes path without clobbering Hermes' default heartbeat/task
instructions.

## What Changed

- Wrapped `hermesLocalAdapter.execute` so `ctx.authToken` is injected
into `adapterConfig.env.PAPERCLIP_API_KEY` when no explicit Paperclip
API key is already configured.
- Injected `ctx.runId` into `adapterConfig.env.PAPERCLIP_RUN_ID` so the
auth guard's `X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID` instruction
resolves to the current run id.
- Added a Paperclip API auth guard to existing custom Hermes
`promptTemplate` values without creating a replacement prompt when no
custom template exists.
- Documented the intentional `as unknown as` cast needed until
`hermes-paperclip-adapter` ships an `AdapterExecutionContext` type that
includes `authToken`.
- Added registry tests for JWT injection, run-id injection, explicit key
preservation, default prompt preservation, and the no-`authToken`
early-return path.

## Verification

- [x] `pnpm --filter "./server" exec vitest run adapter-registry` - 8
tests passed.
- [x] `pnpm --filter "./server" typecheck` - passed.
- [x] Trigger a Hermes agent heartbeat and verify Paperclip writes
appear under the agent identity rather than a shared board-user
identity, with the correct run id on mutating requests.

## Risks

- Low migration risk: this changes only the Hermes local adapter wrapper
and tests.
- Existing explicit `adapterConfig.env.PAPERCLIP_API_KEY` values are
preserved to avoid breaking intentionally configured agents.
- `PAPERCLIP_RUN_ID` is set from `ctx.runId` for each execution so
mutating API calls use the current run id instead of a stale or literal
placeholder value.
- Prompt behavior is intentionally conservative: the auth guard is only
prepended when a custom prompt template already exists, so Hermes'
built-in default prompt remains intact for unconfigured agents.
- Remaining operational risk: the identity and run-id behavior should
still be verified with a live Hermes heartbeat before relying on it in
production.

## Model Used

- OpenAI Codex, GPT-5 family coding agent, tool use enabled for local
shell, GitHub CLI, and test execution.
