TimeReverse v0.5.0 — Verifiable context handoffs

TimeReverse now produces compact context packs that can be checked instead of blindly trusted.

Highlights:

• Labels facts as verified, unverified, assumptions, or stale
• Checks referenced files and reports missing paths
• Includes Git commit, branch, and dirty/clean working-tree state
• Records bounded test commands and results without copying full tool output
• Adds timereverse doctor and MCP diagnostics for database, schema, registry, and Git
• Recovers from malformed Codex JSONL lines and corrupt event metadata
• Includes automatic SQLite schema migration through version 5
• CI now builds and clean-installs the wheel and scans tracked files for likely secrets on Windows, Linux, and macOS

This release also includes all milestones delivered since v0.1: structured handoffs (v0.2), multiple isolated projects (v0.3), and immutable checkpoints with diffs (v0.4).
