Fix five latent bugs from temporal-precision code review

Browse Source 
1. parse_salience_100: handle 3+ decimal digit salience strings correctly.
   The two-branch 'else { stripped }' case treated any N-digit decimal value
   as hundredths, so "0.125" (stripped=125) clamped to 100 instead of 12.
   Now divides by 10^(N-2) for N>2, mapping "0.125"->12, "0.375"->37, etc.

2. mem_consolidate Canonical scan: replaced single engram_scan_nodes_json(50,0)
   call with a paginated loop (page_size=50, advancing offset) so Canonical nodes
   beyond index 50 are no longer silently excluded from the periodic boost.

3. mem_consolidate Canonical strengthening: add salience ceiling guard so nodes
   already at the runtime maximum (serialised as "1" by %g) are skipped. Prevents
   monotonic unbounded salience growth across successive consolidation passes.

4. soul.el affective cutoff: replaced json_get(aff_node, "ts") with
   json_get(aff_node, "created_at") / "updated_at" fallback, consistent with
   handle_chat. The old "ts" field is not a standard engram node field; missing
   it caused the fallback to ts_now (always passes cutoff), over-including stale
   nodes. New behaviour defaults to 0 on missing timestamps (conservative exclude).

5. History byte-cap: implemented the existing TODO 32KB byte-cap. Added
   hist_trim_to_byte_cap() and applied it after count-based trim in both
   handle_chat and handle_chat_agentic. Prevents 100KB+ state entries at 40 turns
   during long technical sessions with large assistant responses.
