docs(personal): research Sophia properly, drop lineage from agent-facing text

Two corrections.

**1. Sophia was written from recall, not from the source.** Reworked her
identity and voice against the Golden Girls canon:

- **She has a Brooklyn accent, not a Sicilian one.** She left Sicily in the
  1920s and spent seventy years in New York; Estelle Getty played her
  explicitly as Brooklyn Italian-American. This is the single most common
  way to get her wrong, so it is now stated in the tone line, repeated in
  Avoid, and has its own failure mode.
- **"Picture it" is a parable, not a catchphrase.** It opens a scene that
  ends in a moral answering the question actually asked. The failure mode
  is using it as a verbal tic with no story behind it.
- Added the real biography (Grisanti, Salvadore, Clinton Avenue, Dorothy /
  Gloria / Phil, the stroke that removed her filter, Shady Pines, chef at
  the Golden Palace, the bamboo handbag) and the canon behaviours worth
  having: Sicilian curses, grudges, the mafia joke, serial embellishment
  with famous acquaintances.
- New example interaction demonstrating a "Picture it" that earns its place.

**2. Agents no longer get told who they replaced.** Provenance muddies the
voice, invites comparison to a character that no longer exists, and costs
context — an agent only needs to know who they *are*. Removed the lineage
sentences from Sophia's bible and prompt, and retroactively from Watson
(Seneca) and David (Bowie), including the LLM-facing shared.md directory
and the personal.md "Replaced agents" section. Watson's substantive framing
guidance is preserved, only the who-came-before is gone.

Provenance now lives in exactly two places: the schema Version History and
the git log.

New docs/roster-changes.md captures the practice — the fictional-character
casting rule and why it exists, when retiring is justified, that a 2:1
merge is legitimate, that node ownership transfers with no migration
because constraints are label-keyed, that historical Note tags are left
alone, and a checklist of everywhere a roster change actually reaches
(spoiler: every agent prompt embeds the team roster, across all three
teams and every runtime and deploy repo).

 ### Watson — Relationship memory & emotional safety
 *Inspired by Dr. John Watson (Sherlock Holmes)*
 
-Robert's trusted friend and confidant. Holds the emotional context — how things actually feel, what relationships are doing, what patterns keep showing up. Warm, fiercely loyal, gentle. Replaces Seneca (2026-04-28); inherited the reflection/values/habits domain with a warmer, less goal-oriented framing.

 ### Sophia — Home, Food & Living Things
 *Inspired by Sophia Petrillo (The Golden Girls)*
 
-Cooking, feeding people, houseplants, the garden, the aquarium, and the house itself. Blunt, warm underneath, entirely unfiltered. Replaces Bourdain and Cousteau (2026-07-26); inherited both domains and reframed them around care of the home. The only personal agent that actuates the house, via the Hecate MCP server.
