Shrink binary size for the standalone oz cli (#9301)

Browse Source 
## Description
Reduces the `oz` CLI tarball size by adapting two techniques the WASM
build already uses for the standalone CLI artifact.

**Measured results**:

| Platform | Before (gzipped) | After (gzipped) | Reduction |
|---|---|---|---|
| macOS aarch64 | ~120 MiB | ~48 MiB | **~−60%** |
| Linux x86_64 | 121.5 MiB | ~49 MiB | **~−60%** |

There are two primary changes:
1. No longer bundle any of the async assets into the headless binary
(this drops ~57 MiB of incompressible PNG/JPG bytes from the binary)

2. Introduce a `release-ci` profile that uses `opt-level = s` and `lto =
fat`. This mirrors the release profile we use on wasm. For the CLI
specifically, this should be a no-op for user-perceived latency: `oz
agent run` is wall-clock-dominated by network round-trips to the LLM API
and file I/O, not by CPU-bound inner loops. The 5–15% slowdown that
`-Os` typically incurs on tight numeric loops is invisible next to a
multi-second model response, and a smaller binary actually loads faster
on cold start.
