Vouch request: vyncint

[vyncint]

What do you want to work on?

I want to work on the one part of #1098 which is: rejected policy chunks do not show the guidance that was saved for them.

I read v0.0.111: rejection_reason (PolicyChunk field 18) is written by update_draft_chunk_status, round-trips through policy_store.rs, and reaches the TUI in GetDraftPolicyResponse.chunks, but crate openshell-tui never references the field, so the reviewer's own note is dropped at the last step. The fix stays inside the TUI crate.

Two items on that issue are already done: the validation_result badge, and the 2-second refresh for active sandbox view. human_summary and intent_summary do not exist in the repo yet, so I am leaving those out. They are a proto change and need design agreement first.

Why this change?

I use OpenShell daily on MacBook (Apple Silicon Chip). There is no compute driver for apple/container, so I wrote and maintain an out-of-tree one which is the shape #1887 concluded was right. That means I approve and reject policy chunks in the TUI a lot, and I keep rejecting a chunk and then, minutes later, not remembering why. The reason is already stored.

On the Rust side, I am an active contributor to NVlabs/cuda-oxide and I also made termlens which is a test harness for ratatui TUIs. So I can verify a rendering change rather than just screenshot it.
