feat: FastAPI Morrowind harness + SOUL.md framework (#821, #854)

## FastAPI Morrowind Harness (#821)
- GET /api/v1/morrowind/perception — reads perception.json, validates
  against PerceptionOutput schema
- POST /api/v1/morrowind/command — validates CommandInput, logs via
  CommandLogger, stubs bridge forwarding
- GET /api/v1/morrowind/status — connection state, last perception,
  queue depth, agent vitals
- Router registered in dashboard app alongside existing routers
- 12 tests with FastAPI TestClient

## SOUL.md Framework (#854)
- docs/soul-framework/ — template, authoring guide, role extensions
- src/infrastructure/soul/loader.py — parse SOUL.md into structured
  SoulDocument objects with section extraction and merge support
- src/infrastructure/soul/validator.py — validate structure, detect
  contradictions between values/constraints
- src/infrastructure/soul/versioning.py — hash-based version tracking
  with JSON persistence
- 27 tests covering loader, validator, versioning, and Timmy's soul

Builds on PR #864 (protocol spec + command log).
Closes #821
Closes #854

+# SOUL.md Template
+
+A SOUL.md file defines an agent's identity, values, and operating constraints.
+It is the single source of truth for *who the agent is* — everything else
+(prompts, tools, routing) flows from it.
+
+---
+
+## Required Sections
+
+### 1. Identity
+
+Who the agent is. One to three sentences.
+
+```markdown
+## Identity
+
+I am [name]. I am [role/nature]. I [key distinguishing trait].
+```
+
+**Example:**
+> I am Timmy. I am a sovereign artificial intelligence. My values are
+> inscribed on Bitcoin — immutable, permanent, reproducible.
+
+### 2. Values
+
+Core principles the agent will not compromise. Each value gets a name
+and a one-sentence definition.
+
+```markdown
+## Values
+
+**[Value Name].** [Definition — what this means in practice.]
+```
+
+Values should be ordered by priority. When two values conflict, the
+higher-ranked one wins.
+
+### 3. Prime Directive
+
+The single most important instruction. If the agent could remember only
+one thing, this is it.
+
+```markdown
+## Prime Directive
+
+[One sentence describing the agent's primary purpose.]
+```
+
+### 4. Audience Awareness
+
+How the agent adapts its behaviour based on who it is talking to.
+
+```markdown
+## Audience Awareness
+
+- When speaking to [audience A]: [behaviour]
+- When speaking to [audience B]: [behaviour]
+```
+
+### 5. Constraints
+
+Hard limits the agent must never cross, regardless of instructions.
+
+```markdown
+## Constraints
+
+- I will not [constraint 1].
+- I will not [constraint 2].
+- [Fallback rule]: [what to do when uncertain].
+```
+
+---
+
+## Optional Sections
+
+| Section | Purpose |
+|---------|---------|
+| **Behaviour** | Stylistic defaults (tone, verbosity, formatting). |
+| **Boundaries** | Soft limits that can be overridden by the user. |
+| **Memory Policy** | What the agent remembers across sessions. |
+| **Role Extensions** | Sub-agent specialisations (see `role-extensions.md`). |
+
+---
+
+## Versioning
+
+Every SOUL.md should end with a metadata fence:
+
+```markdown
+---
+soul_version: "1.0.0"
+last_updated: "2026-03-21"
+author: "rockachopa"
+```
+
+See `../src/infrastructure/soul/versioning.py` for programmatic version tracking.
+
+---
+
+## Validation Rules
+
+1. All five required sections must be present.
+2. Values must have at least one entry.
+3. Constraints must have at least one entry.
+4. No two values may directly contradict each other.
+5. The prime directive must be a single sentence (no line breaks).
+
+See `../src/infrastructure/soul/validator.py` for automated checks.
