fix(hermes): stop advertising unsupported instructions bundles (#3908)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - Local adapter capability flags decide which configuration surfaces
the UI and server expose for each adapter.
> - `hermes_local` currently advertises managed instructions bundle
support, so Paperclip exposes the AGENTS.md bundle flow for Hermes
agents.
> - The bundled `hermes-paperclip-adapter` only consumes
`promptTemplate` at runtime and does not read `instructionsFilePath`, so
that advertised bundle path silently does nothing.
> - Issue #3833 reports exactly that mismatch: users configure AGENTS.md
instructions, but Hermes only receives the built-in heartbeat prompt.
> - This pull request stops advertising managed instructions bundles for
`hermes_local` until the adapter actually consumes bundle files at
runtime.

## What Changed

- Changed the built-in `hermes_local` server adapter registration to
report `supportsInstructionsBundle: false`.
- Updated the UI's synchronous built-in capability fallback so Hermes no
longer shows the managed instructions bundle affordance on first render.
- Added regression coverage in
`server/src/__tests__/adapter-routes.test.ts` to assert that
`hermes_local` still reports skills + local JWT support, but not
instructions bundle support.

## Verification

- `git diff --check`
- `node --experimental-strip-types --input-type=module -e "import {
findActiveServerAdapter } from './server/src/adapters/index.ts'; const
adapter = findActiveServerAdapter('hermes_local');
console.log(JSON.stringify({ type: adapter?.type,
supportsInstructionsBundle: adapter?.supportsInstructionsBundle,
supportsLocalAgentJwt: adapter?.supportsLocalAgentJwt, supportsSkills:
Boolean(adapter?.listSkills || adapter?.syncSkills) }));"`
- Observed
`{"type":"hermes_local","supportsInstructionsBundle":false,"supportsLocalAgentJwt":true,"supportsSkills":true}`
- Added adapter-routes regression assertions for the Hermes capability
contract; CI should validate the full route path in a clean workspace.

## Risks

- Low risk: this only changes the advertised capability surface for
`hermes_local`.
- Behavior change: Hermes agents will no longer show the broken managed
instructions bundle UI until the underlying adapter actually supports
`instructionsFilePath`.
- Existing Hermes skill sync and local JWT behavior are unchanged.

## Model Used

- OpenAI Codex, GPT-5.4 class coding agent, medium reasoning,
terminal/git/gh tool use.
