Michael NguyenandPaperclip 1ebf5254b6 fix(plugin-loader): deliver stored config to freshly-started plugin workers (#10092)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for work.
> - One capability is first-party **plugins** that run as isolated workers spawned by the host `plugin-loader`, reading company-scoped config through a governed `ctx.config.get(companyId)` channel.
> - A **proactive** plugin (e.g. a chat gateway that opens a Slack Socket Mode connection at startup) does its company work from `setup()`, where there is **no company-scoped invocation** — so `ctx.config.get()` is rejected with `company context is required`.
> - The worker swallows that error and falls back to its default (feature-off) config, so the plugin comes up **inert** even though correct config exists in the database.
> - This is a regression from #9557 ("governed access contracts"), which changed `plugin-loader.ts` `activatePlugin` from loading stored config into the worker bootstrap to `const config = {}`.
> - This pull request replays each configured company's stored config to the freshly-started worker over the **same `configChanged` host→worker path an operator config-save already uses**.
> - The benefit is that proactive plugins receive their config on worker start (both server boot and operator enable) without weakening the governed-access surface.

## Linked Issues or Issue Description

No public GitHub issue — describing in-PR (bug):

**Bug.** After a proactive plugin's worker spawns, it never receives its stored config. Governed access (`packages/plugins/sdk/src/host-client-factory.ts`) only resolves `config.get` inside a company-scoped invocation (event/action/tool, or explicit `params.companyId`). Proactive plugins operate from `setup()` where no such scope exists, so `config.get()` fails with `company context is required`, the worker falls back to defaults, and the feature stays disabled despite valid DB config.

- Regression introduced by #9557.
- Related follow-up (latent multi-company hardening): #10096.

## What Changed

- `plugin-registry.ts`: add read-only `listConfigs(pluginId)` returning all stored company config rows for a plugin (scoped `where eq(pluginConfig.pluginId, pluginId)`).
- `plugin-loader.ts`: after the worker starts in `activatePlugin`, replay each company's stored config through the existing `configChanged` host→worker RPC — one `{ config, companyId }` per row, the same payload shape as the operator config-save path in `routes/plugins.ts`. Best-effort and idempotent; covers both server-boot `loadAll` and operator enable.
- test: DB-backed `plugin-config-startup-delivery.test.ts` covering `registry.listConfigs` completeness and cross-plugin isolation.

## Verification

- `tsc --noEmit` on `@paperclipai/server` — clean.
- New `plugin-config-startup-delivery.test.ts` (embedded-postgres, 3 cases) — pass.
- Full PR CI green: typecheck, all server/e2e/serialized test shards, build, canary dry-run, verify, and the security scanners (Snyk, Socket, Superagent, Greptile).

## Risks

- **Low functional risk.** Adds an outbound host→worker push that mirrors the already-shipped operator-save path. A worker without an `onConfigChanged` handler (or momentarily unavailable) simply keeps the runtime `ctx.config.get(companyId)` model.
- **Startup fan-out.** One `configChanged` per configured company at activation (sequential, default RPC timeout). `plugin_config` rows are writable only by instance-admins, so fan-out size is operator-controlled — not a remote surface.
- **No secret-handling change.** `configJson` is delivered as-is, exactly as `config.get`/operator-save already deliver it. No new secret sink; catch-blocks log only ids + `err.message` at debug, never `configJson`.
- **Latent multi-company behavior (pre-existing, not introduced here).** The worker-side `configChanged` dispatch forwards only `config` (drops `companyId`), and `listConfigs` has no `ORDER BY`, so a plugin configured for **more than one** company would apply a nondeterministic last-write-wins global config. This is existing SDK behavior — operator-save already pushes into the same handler — and is **not reachable by the single-company consumer this fix targets**. Greptile flagged this shape (4/5). It is tracked and fixed as a separate, non-blocking hardening PR (#10096): thread `companyId` through `onConfigChanged`, deterministic ordering, bounded fan-out.
