Snapshots YAML template content in a new `plan_template_versions` table
whenever a plan is created from a template. Plans reference their version
via `template_version_id` so existing plans are unaffected by future
template file edits.
Key changes:
- Migration 0006: create `plan_template_versions` table (slug, version,
name, content JSON, content_hash SHA-256); add nullable FK
`template_version_id` to `agent_plans`
- Model `PlanTemplateVersion`: `findOrCreateFromTemplate()` deduplicates
identical content by hash; `historyFor()` returns versions newest-first
- `AgentPlan`: add `template_version_id` fillable and `templateVersion()`
relationship
- `PlanTemplateService::createPlan()`: snapshot raw template before
variable substitution; store version id and version number in metadata;
add `getVersionHistory()` and `getVersion()` public methods
- Tests: `TemplateVersionManagementTest` covering model behaviour, plan
creation snapshotting, deduplication, history ordering, and service
methods

Enhance `validateVariables()` in `PlanTemplateService` to produce
actionable errors instead of the generic "Required variable '...' is missing".
Changes:
- Extracted `buildVariableError()` helper that composes the message from
the variable's `description`, `format`, `example`, and `examples` fields
- Added `naming_convention` key to the returned array so callers have
a constant reminder that variable names use snake_case
- Added a `NAMING_CONVENTION` private const to avoid string duplication
Tests (6 new cases in `PlanTemplateServiceTest`):
- description included in error message
- single `example` value included
- `examples` list (first two) included
- `format` hint included alongside example
- `naming_convention` present in both valid and invalid results
- bare variable (no description) still produces useful "missing" message
