[#34]: skip non-full view_mode entries (Codex v0.130.0 compat)

[delexw]

Fixes #34

What

Codex v0.130.0 (upstream PR #21566) introduced three view modes for thread turn items written into JSONL session files: unloaded (metadata-only stub), summary (partial data), and full (complete data). Without handling these, codex-trace would silently process placeholder stubs as real turn entries, producing truncated or phantom turns for any session recorded with v0.130.0+.

How

Added a guard in RawEntry::parse (src-tauri/src/parser/entry.rs) that returns None for any JSONL entry where view_mode is present but not "full". Entries without a view_mode field (all pre-v0.130.0 sessions) are unaffected.

if let Some(vm) = v.get("view_mode").and_then(|t| t.as_str()) {
    if vm != "full" {
        return None;
    }
}

This sits alongside the existing record_type: "state" guard and follows the same pattern: unknown/incomplete placeholders are dropped at the earliest parse stage so the rest of the pipeline never sees them.

Tests

• view_mode_unloaded_returns_none — unloaded stubs are discarded
• view_mode_summary_returns_none — summary stubs are discarded
• view_mode_full_is_parsed_normally — full entries parse as before
• absent_view_mode_is_parsed_normally — legacy entries (no field) are unaffected
• multi_page_thread_all_turns_present_stubs_ignored — end-to-end: a session with stubs interspersed across pages yields exactly the complete turns and none of the stub placeholders

All 64 Rust tests and 122 frontend tests pass.
