Context Continuity V2 — bounded release

First public release of Context Continuity.

Highlights:

• one-command audited resume with deterministic Resume Cards;
• append-only, hash-linked Markdown checkpoints;
• explicit comparison and compaction at durable state changes;
• evidence-bound review and atomic publication;
• monotonic completion and state-aware diagnosis;
• English and Simplified Chinese documentation;
• 127/127 deterministic regression tests in the frozen local suite.

This is a bounded release: host lifecycle hooks, universal model reliability,
and same-permission malicious-process authentication remain outside the claim
boundary. See docs/EVALUATION.md
for evidence classes and limitations.
