fix(session-continuity): address all adversarial review findings

Issue 1 (CRITICAL): Restore parse_float_x100 for correct single-decimal float handling. "0.9" now correctly yields 90, not 9. Also restores engram_numeric_valid guard that validates inputs before str_to_int. Issue 2 (CRITICAL): Fix handle_chat_agentic safety screen history key regression. state_get("conversation_history") -> state_get("conv_history") so the safety screen receives actual history instead of always "". Issue 3 (REAL BUG): Replace _sel_N JSON sentinel injection in engram_compile_ranked with |N| index string tracking. Sentinels were leaking into node JSON delivered to the LLM and cleanup only covered indices 0-14, leaving indices 15+ uncleaned. Issue 4 (REGRESSION): Restore rendered conversation history formatting. Conversation history is now rendered as "User: .../Assistant: ..." with 400-char truncation per turn, not raw JSON array injection. Issue 5 (SCOPE/SAFETY): Restore removed defensive code: engram_numeric_valid and parse_float_x100 guards; conv_history_load label-based fetch + partial- write guard + load-failure state flag; conv_history_persist partial-write guard + failure logging; hist_warning in response envelope. Issue 6 (UNDOCUMENTED): Restore bell event cutoff from 259200s (3 days) back to 1209600s (14 days). Also restore PositiveEvent affective context search that was removed alongside the cutoff change. Issue 7 (LOGIC REGRESSION): Fix affective_prefix to run every turn (not just hist_len == 0). The care/joy directives must persist throughout the session, not vanish after turn 1. Issue 8 (MINOR): session_summary_write_dated now uses el_from_float(0.85) for salience and importance (two-decimal) to avoid any ambiguity in float parsing, and the function is re-added with the session-end hook.
fix(recall): deduplicate engram nodes by ID across activation and search passes
