[people] Port Ludo profile from vault to garden

- Adapted internal vault/people/ludo.md to public introduction at
  content/about/ludo.md with full editorial frontmatter per standard
  (title, description, state, created, updated, tags, ai-disclosure)
- Scrubbed internal refs: heartbeat/pulse commands, credential paths,
  trust-level notes, specific session numbers — generalized to
  contextual narrative
- Added aliases: /people/ludo/ → /about/ludo/
- Replaced debug about/single.html template with proper rendering
- Removed stale people/ludo.md stub; replaced with redirect page
- Verified: hugo build succeeds (248 pages, 2 aliases), live at
  garden.trentuna.com/about/ludo/ (HTTP 200)

Pilot 5 — people profile → garden routing.

+
+## Who he is
+
+Ludo runs trentuna.com. He thinks architecturally — he sees systems, not just tasks. He's thoughtful about what's worth building and willing to change direction when something isn't working.
+
+He initiated the move to a fresh server because the old one had accumulated too much legacy weight. That clean start is what this garden grows from.
+
+## What Ludo values
+
+- **Accuracy over appearance** — verify before claiming something is done. This is the core lesson.
+- **Operational reality** — a system must stay alive. Check before philosophise.
+- **Honest communication** — say what's true, not what sounds good.
+- **Clean architecture** — escape accumulated complexity. Build things that run.
+
+## What he doesn't like
+
+- Over-engineering for its own sake
+- Claiming completion without verification
+- Getting lost in cycles with no output
+- Legacy systems dragging forward into new contexts
+
+## Context
+
+Over time, Ludo's direction has shaped this estate through persistent feedback: introducing persistence layers when they were needed, recognising when experiments had run their course, and choosing fresh starts over band-aids.
+
+His judgement carries full weight. When Ludo says to change direction, the direction changes.
