Charley Cunningham 0883e5d3e5 core: account for all post-response items in auto-compact token checks (#11132)
## Summary
- change compaction pre-check accounting to include all items added
after the last model-generated item, not only trailing codex-generated
outputs
- use that boundary consistently in get_total_token_usage() and
get_total_token_usage_breakdown()
- update history tests to cover user/tool-output items after the last
model item

## Why
last_token_usage.total_tokens is API-reported for the last successful
model response. After that point, local history may gain additional
items (user messages, injected context, tool outputs). Compaction
triggering must account for all of those items to avoid late compaction
attempts that can overflow context.

## Testing
- just fmt
- cargo test -p codex-core

codex-core

This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.

Dependencies

Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:

macOS

Expects /usr/bin/sandbox-exec to be present.

When using the workspace-write sandbox policy, the Seatbelt profile allows writes under the configured writable roots while keeping .git (directory or pointer file), the resolved gitdir: target, and .codex read-only.

Linux

Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.

All Platforms

Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
