feat(adapters): support Codex 0.146

[somus]

Summary

• Add the Codex v0.146 source schema, export, registry selection, mappings, and fixtures.
• Capture world-state snapshots and deltas, applied thread settings, subagent and inter-agent activity, rollback markers, and new diagnostic families without quarantine.
• Add a manually redacted real Codex v0.146 source fixture and exact golden trail covering tool pairing, token usage, subagent lifecycle, and routed inter-agent messages.
• Project published thread and world state through explicit safe-field allowlists while retaining capped and redacted provenance.
• Link Codex task-name child sessions, preserve token and image rollups around routed messages, and canonicalize OpenCode fork parent IDs.
• Extend the Claude Code v1 source contract range through current 2.1.x releases.

Related Issue

• N/A; maintainer-directed adapter compatibility update.

Public Impact

• No public contract change
• Spec or schema change
• Public package API change
• Changeset added or explicitly not needed
• CLI behavior change
• Public URL or docs behavior change

Impact description:

• Adds the @agent-trail/source-schemas Codex v0.146 export and expands adapter behavior for current source formats. The canonical Agent Trail schema is unchanged.

Verification

• CI=1 mise run check: 963 passed, 5 expected opt-in live skips, 0 failed.
• Real-session fixture corpus: 12 passed, including the redacted Codex v0.146 source/golden pair.
• Focused Codex v0.146 and source-type checks: 20 passed.
• Live Codex, OpenCode, and Pi harnesses: zero quarantines and zero diagnostics.
• bun run check:changesets passed.

Reviewer Notes

• Full five-lens review-loop completed clean on the implementation fingerprint.
• World and thread settings use explicit publication allowlists; opaque instructions and environment values are omitted from canonical event data.
• The Codex v0.146 generated source type is checked against its canonical JSON schema.
• The committed real-session fixture uses synthetic IDs and redaction placeholders; no raw local session, path, transcript, instruction, or secret data is committed.
