Add memory-dream skill + additive cross-machine memory sync

memory-dream: read-only memory lint/consolidation analyzer (index, backlinks,
stale refs, dup clusters, profile drift); additive-only --apply-safe, all
merges/deletes are proposals. sync-memory.sh: additive repo<->harness-profile
union (no delete/overwrite, conflicts surfaced), wired to a SessionStart hook.
Migrates the useful profile-only memories into the synced repo store.

+description: Correct Syncro API endpoint for adding labor/product line items to tickets

+
+Use `POST /api/v1/tickets/{internal_ticket_id}/add_line_item` to add line items to tickets. Both `name` and `description` fields are required (422 if either missing). Never use timers.
+
+**Why:** `/line_item`, `/line_items`, and PUT `line_items_attributes` all 404. The correct endpoint was found via Syncro Swagger spec at api-docs.syncromsp.com. Mike has explicitly said never use timers.
+
+**How to apply:**
+- Path uses internal ticket ID (e.g., 111387456), not ticket number (32339)
+- Required fields: `name`, `description`, `quantity`, `price`, `taxable` (and `product_id` if catalog item)
+- Response is a flat object — parse `.id` directly (not `.line_item.id`)
+- For testing/practice, use internal ACG account only (customer ID 15353550)
+
+Example:
+```
+POST /api/v1/tickets/111387456/add_line_item
+{"product_id":1049360,"name":"Labor- Warranty work","description":"...","quantity":1,"price":0.0,"taxable":false}
+```
