v0.5.2

Fixed

• /rite:init --upgrade short-circuit path no longer drops drift back-adds (#1461) — when no pending drift was detected, the --upgrade short-circuit path skipped the back-add step that the full path performs, so projects taking the short-circuit could miss newly added config sections and sub-keys. The short-circuit now applies the same drift back-add logic, covered by an added drift-detection test.
• Fixed broken references to the non-existent _resolve-flow-state-path.sh (#1466) — updated stale script references in the hooks documentation to the actual flow-state.sh path.

Changed

• Unified flow state on the per-session model (#1460) — removed the legacy flow_state.schema_version=1 (single-file) path from the hooks (session-start, session-end, post-compact, pre-compact, post-tool-wm-sync), init.md, and the config template, consolidating on per-session flow state. Stale schema_version test fixtures/labels were neutralized (#1465), commit.contextual was added to the SPEC Deprecated key list (#1469), and SPEC.md / getting-started.md were updated to follow the --upgrade drift back-add behavior change (#1467).
