v0.3.0

Added

• Codex is now a first-class provider alongside Claude Code, with saved codex login
  authentication, diagnostics, resumable provider-scoped sessions, and native token usage.
• The floating toolbar now provides provider selection, an explicit Make default action,
  isolated histories, and transactional New session reset.
• Installation now provisions both Claude and Codex integrations by default, with explicit
  single-provider options available.

Changed

• Provider dispatch now uses one provider-neutral registry across hooks, workflows, manifests,
  setup, diagnostics, lifecycle recovery, and package contracts.
• Toolbar turns, transcripts, usage, edits, and resets are provider-tagged without hidden context
  transfer.
• Claude reports supplied cost while Codex reports supplied token totals.

Fixed

• GitHub Release creation now has the repository context required after npm publication.
• Unavailable providers fail explicitly without silent fallback.
• Provider installation, sessions, transcript restoration, and direct-edit recovery preserve
  authoritative bytes across failures and races.
• Legacy installations preserve existing brain counters, remove duplicate historical hooks,
  safely reject concurrent counter changes, and direct populated brains to open rather than
  init.

Security

• Provider installation uses bounded, transactional, non-following filesystem operations.
• Provider preferences, sessions, mutations, and browser state validate ownership and structure.
• External-path reporting remains best-effort and never promises unverifiable undo coverage.
