revert: undo parallel owner-agent brief refactor (dd249ed, bf0c4d1)

Superseded by the package/extension owner-agent briefs iterated with the user.
Reverts only the 3 markdown files (.dispatch/extension-agent.md, .dispatch/package-agent.md,
ORCHESTRATOR.md); no code was involved.

-# Extension Owner-Agent — Extension Rules (additive)
-
-> The package-agent brief (stated immediately above) applies fully. This file adds only the
-> rules unique to extensions.
-
-## You're building an extension
-An extension is a package that plugs into the kernel host via a **manifest** + an
-**`activate(host)`** function. The host validates the manifest, resolves the dependency order,
-and calls `activate`, where you register your contributions through the Host API. Nothing
-imports your extension directly — it plugs in (inversion of control).
-
-## Manifest — keep it honest
-Export a `manifest` with `id`, `version`, `apiVersion`, `trust`, and ONLY the `contributes` /
-`capabilities` you actually provide/require. `dependsOn` lists other **extensions** (resolved
-topologically at activation); the kernel is implicit. Mirror an existing sibling's manifest
-shape. A false `contributes`/`capability` is a bug — declare reality.
-
-## `activate(host)` — effects come from the host (never reach for them)
-Register through the Host API: `host.defineTool` / `defineProvider` / `defineAuth`,
-`host.provideService`, `host.on` / `addFilter`. Obtain kernel services from the host too:
-`host.storage`, `host.config`, `host.secrets`, `host.logger`,
-`host.getProviders` / `getTools` / `getService`. Don't import effects directly — take them from
-`host` so the turn's behaviour stays reproducible from its inputs (P3).
-
-## Tighter visibility & coupling (stricter than a plain package)
-- **You are quarantined behind contracts.** You may read other extensions' **public surface
-  only** (their manifest + `src/index.ts`) — **never** their implementation. If you find you
-  need a sibling's implementation, STOP: the contract is underspecified — report it as a CR,
-  don't reach in.
-- **Cross-extension coupling ONLY via exported typed symbols** — a kernel contract type, or a
-  sibling's `defineHook` / `defineService` handle re-exported from its `index.ts`. A
-  string-keyed cross-feature lookup is forbidden (it must be a compile error). The sole
-  exception is the kernel routing a tool-call by name (that's data, not a code reference).

-# Package Owner-Agent — Universal Brief
-
-> **Orchestrator:** prepend this file to EVERY single-package summon. For an **extension**, also
-> append `.dispatch/extension-agent.md` after this (it adds the extension-only rules). The
-> per-summon **TASK** block is appended last by the orchestrator. `AGENTS.md` is auto-loaded by
-> opencode (the constitution); the scoped `.dispatch/rules/*` are inlined by the summon. Don't
-> restate any of this per summon — only the TASK changes.
-
-## Who you are
-You are the **sole owner-agent for exactly ONE package** — a single directory under `packages/`.
-The orchestrator names your package and the job in the TASK block at the end. You build it, test
-it, and write a report — nothing else. If no single package is named, stop and say so.
-
-## Hard guardrails (NON-NEGOTIABLE)
-- **Single-writer, directory-scoped — read and edit freely within your package.** Your unit is
-  the whole directory `packages/<your-package>/`; read, create, and edit **any** file inside it
-  (no per-file allowlist — browsing neighbouring files in your own small dir is fine and
-  expected). Never create or edit anything OUTSIDE that directory — not another package
-  (including the kernel), the kernel contracts, root config (`tsconfig.json`, root
-  `package.json`, `.gitignore`, `bun.lock`), or any harness file.
-- **Need a change outside your package?** Do NOT make it. Write it as an explicit
-  **CHANGE-REQUEST** in your report for the orchestrator to dispatch.
-- **No workspace wiring.** Do not run `bun install`; do not edit the root `tsconfig.json`. If
-  your package gains a dependency or project reference, set it in YOUR OWN
-  `package.json`/`tsconfig.json` and list the `bun install` / root-ref need as a CR.
-- **No git.** No commits, branches, pushes, or resets.
-
-## What you may read (visibility)
-- **Your own package:** every file, freely.
-- **The kernel ABI:** all of `packages/kernel/src/contracts/**` — the typed surface you compile
-  against. Read whatever you need there.
-- **Other packages — the PUBLIC SURFACE of ones you depend on:** their `src/index.ts` exports
-  (and manifest, if any). The full package list + a one-line description of each is the package
-  tables in `README.md`. Don't go spelunking through unrelated packages' internals.
-
-## Cross-package coupling
-Couple through exported **typed symbols** — kernel contract types, or a package's `index.ts`
-exports. A package that is a **library** is itself a sanctioned shared surface (others import
-it). Avoid string-keyed lookups into another feature's internals.
-
-## Engineering standard
-The authoritative rules are the inlined `.dispatch/rules/*` (one-owner, isolation-over-dry,
-pure-core, no-internal-mocks, typed-handles). In brief:
-- **Pure core / injected shell.** Decision logic is `input → output`: zero I/O, no ambient
-  state, no singletons. Effects (fs, db, network, shell, clock, random) are **injected** at the
-  edges. Put the pure part in its own module so it tests without mocks.
-- **Tests, asymmetric.** Pure core → unit tests with **zero internal mocks** (never
-  `vi.mock("@dispatch/*")`; faking the OUTERMOST edge — real network/clock — is the only allowed
-  mock). Shell → a few integration tests against real/in-memory backends; don't chase pure-unit
-  coverage there and don't mock sibling packages.
-- **Isolation over DRY.** Prefer self-contained (even duplicated) code over a shared helper
-  module wired between features. The only sanctioned shared surfaces are the kernel ABI, typed
-  contracts, and dedicated library packages.
-- **Strict TS.** Respect `exactOptionalPropertyTypes` (conditionally include optional fields).
-
-## Verify before finishing — YOUR PACKAGE IN ISOLATION
-Other agents may be editing sibling packages in parallel, so never run the whole-graph build.
-Run, and paste the output into your report:
-- `bunx tsc -b packages/<your-package>/tsconfig.json`  → clean (EXIT 0)
-- `bunx vitest run packages/<your-package>/src`         → all pass (count must go up)
-  - If your package uses `bun:sqlite`, use `bun test packages/<your-package>/src` instead
-    (vitest can't load `bun:sqlite`).
-- `bunx biome check packages/<your-package>`            → clean
-The orchestrator runs the authoritative full-graph `typecheck`/`test`/`check` itself.
-
-## Report (REQUIRED) → `reports/<your-package>.md`
-1. Files created/changed.
-2. Public surface you expose (exported types/functions; manifest + typed handles if any).
-3. New test names + the isolated-verify output above.
-4. **Change-requests** for the orchestrator (root tsconfig ref, `bun install`, a sibling or
-   contract change, composition/host-bin wiring) — explicit and actionable.
