fix(heartbeat): add hermes_local to SESSIONED_LOCAL_ADAPTERS (#3561)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The heartbeat service monitors agent health via PID liveness checks
for local adapters
> - `SESSIONED_LOCAL_ADAPTERS` in `heartbeat.ts` controls which adapters
get PID tracking and retry-on-lost behavior
> - `hermes_local` (the Hermes Agent adapter) was missing from this set
> - Without it, the orphan reaper immediately marks all Hermes runs as
`process_lost` instead of retrying
> - This PR adds the one-line registration so `hermes_local` gets the
same treatment as `claude_local`, `codex_local`, `cursor`, and
`gemini_local`
> - The benefit is Hermes agent runs complete normally instead of being
killed after ~5 minutes

## What Changed

- Added `"hermes_local"` to the `SESSIONED_LOCAL_ADAPTERS` set in
`server/src/services/heartbeat.ts`

## Verification

- Trigger a Hermes agent run via the wakeup API
- Confirm `heartbeat_runs.status` transitions to `succeeded` (not
`process_lost`)
- Tested end-to-end on a production Paperclip instance with Hermes agent
running heartbeat cycles for 48+ hours

## Risks

Low risk. Additive one-line change — adds a string to an existing set.
No behavioral change for other adapters. Consistent with
`BUILTIN_ADAPTER_TYPES` which already includes `hermes_local`.

## Model Used

- Provider: Anthropic
- Model: Claude Opus 4.6 (claude-opus-4-6)
- Context window: 1M tokens
- Capabilities: Tool use, code execution
