Governance anchor removal on an expired entry surfaces a raw host error

[therealjhay]

Problemremove_anchor on an expired/archived entry fails at the host layer rather than a typed error (related to issue 53's TTL).

1. Raw host error.
2. No typed NotFound.
3. Client ambiguity.

Solution

• Map archived/expired reads to a typed error.
• Test removal on expired anchors.

Acceptance Criteria

• Typed error on expired anchor ops.
• cargo test --workspace passes.

Note for Contributors: Write a clear PR description. Show the expired-anchor test.

Hello Maintainer,

I'd like to work on issue #583. The goal is to fix governance anchor removal so that attempting to remove an expired entry returns a proper, meaningful error instead of surfacing a raw host error.

I'll add the right error handling and a test to cover the expired-entry case, then share the details in my PR description.

Could you assign this to me? I'll follow up if I have questions.

Thanks,
Micheal
