Port bounded auto-review detail shape

[shiny-code-bot]

Summary

• Port the bounded auto-review detail surface to the Every Code feature shape: optional run-level reads plus specific finding reads.
• Return LLM-friendly formatted detail text instead of pretty JSON, with explicit detailKind, findingCount, and omittedFindings metadata.
• Preserve current Codex Lab safety rules: scoped store lookup, completed/current target gating, hard byte caps, and strict present-but-empty findingId rejection.
• Regenerate app-server protocol JSON/TypeScript schemas.

Verification

• cargo test --manifest-path codex-rs/Cargo.toml -p codex-auto-review
• cargo check --manifest-path codex-rs/Cargo.toml -p codex-app-server-protocol -p codex-app-server
• just write-app-server-schema
• cargo test --manifest-path codex-rs/Cargo.toml -p codex-app-server-protocol schema_fixtures_match_generated
• cargo test --manifest-path codex-rs/Cargo.toml -p codex-app-server --test all auto_review_finding_detail_read
• cargo fmt --manifest-path codex-rs/Cargo.toml --all -- --check
• git diff --check
