feat(personal): Sophia replaces Bourdain and Cousteau

Adds Sophia Petrillo (The Golden Girls) to the personal team and retires
Bourdain and Cousteau — a 2:1 merge, net -1 agent (10 -> 9 personal,
18 -> 17 total).

Why: the personal team casts fictional characters. Bourdain and Cousteau
are real people, one with significant baggage and one who died by suicide,
and neither had a dedicated MCP server or capability. Sophia is fictional,
plausibly owns both domains (an Italian grandmother knows food; tending
plants and the tank is housekeeping), and is the first personal agent to
actuate the house via the new Hecate MCP server.

Graph: Sophia inherits all 11 node types unchanged (Recipe, Restaurant,
Ingredient, Meal, Technique + Species, Plant, Tank, Garden, Ecosystem,
Observation). Uniqueness constraints are keyed on node label, not agent,
so there is no schema or data migration. Historical Note tags
(from:bourdain, to:cousteau) are deliberately left intact as an accurate
record. Schema bumped to 2.5.0.

Also:
- New docs/tools/hecate.md + prompts/tools/hecate.md, documenting the
  physical-actuation discipline (never guess a room or device slug) and
  stating plainly what Hecate cannot do yet: no sensor readings (Demeter
  is REST-only), no weather, and set_timer is routine-bound with no
  cancel — the conversational timer is coming to Daedalus.
- Shawn gains Periplus in the docs. The server was already wired in
  iolaus but never described in any prompt, so the model was handed a
  tool it was never told about — including the never-estimate-coordinates
  rule.
- Corrected stale counts (15/16/18 assistants -> 17) and the stale
  "Bowie's Domain" schema heading missed when David replaced Bowie.
- Removed utils/neo4j-schema-init.py.bak, a pre-Watson artifact.
