Bo 2d2b806ab8 feat(evolve): per-repo preferences.yaml schema + loader + ao evolve config --show (soc-6svt #preferences-yaml) (#396) ...

## Why
Different repos have different /evolve physics. Hardcoded defaults force
ADRs per-repo to override. Per-repo YAML separates skill-doctrine from
repo-policy.

## What changed
| Surface | Change |
|---|---|
| `schemas/evolve-preferences.v1.schema.json` | New JSON Schema draft-07
for the v1 preferences shape |
| `cli/internal/evolve/preferences.go` | New loader: `Load(ctx) (*Prefs,
error)` with file:line error context |
| `cli/cmd/ao/evolve_config.go` | New `ao evolve config --show [--json]`
subcommand |
| `.agents/evolve/preferences.yaml.template` | New starter template |
| `.gitignore` | Negation rules for the template path |

## Resolution order
defaults < preferences.yaml < CLI flag (caller-applied)

Invalid keys/types -> exit 1 with `preferences.yaml:line:col` context.
Never silent fallback.

## How tested
- L2: malformed YAML -> `ao evolve config --show` exits 1, stderr has
file:line
- L1: `preferences.Load()` table tests cover defaults, valid, invalid
types, out-of-range, unknown keys
- `go test ./cli/internal/evolve/ ./cli/cmd/ao/` green (299+ tests
across both)
