Henry Levy 49e248d4c3 Add opt-in compaction after final responses (#46541 )

## What changed

Add `model_post_turn_compact_threshold_percent` to trigger compaction after a final response when context usage reaches the configured percentage of the usable window or an existing auto-compaction limit. Accept values from `0` to `100`; omitted or zero disables the feature.

Skip post-turn compaction when input is pending, the turn is cancelled, or token-budget mode is enabled. Disable it for approval reviewers to avoid delaying approval completion, and record a distinct `PostTurn` analytics phase.

Buffer local post-turn summaries until compaction succeeds and require a nonempty assistant summary before replacing history. Log compaction failures without failing the completed turn, while still propagating interruptions and turn aborts.

ThreadManager Sample

Small one-shot binary that starts a Codex thread with ThreadManager from codex-core-api, submits a single user turn, and prints the final assistant message.

cargo run -p codex-thread-manager-sample -- "Say hello"

Use --model to override the configured default model:

cargo run -p codex-thread-manager-sample -- --model gpt-5.2 "Say hello"

The prompt can also be piped through stdin:

printf 'Say hello\n' | cargo run -p codex-thread-manager-sample
