Enhance Oracle-to-PostgreSQL migration skills and documentation (#2284)

Browse Source 
- Update migration agent guidelines to prioritize extension tool usage for code migration.
- Refine migration phases with detailed steps for pre-migration review and schema migration.
- Add new reviewing skill references for PostgreSQL materialized view refresh and UNION ALL planner risks.
- Ensure consistency in collation handling and testing strategies across skills.

| `creating-oracle-to-postgres-master-migration-plan` | Discovers all projects in a .NET solution, classifies each for Oracle-to-PostgreSQL migration eligibility, and produces a persistent master migration plan. |
| `migrating-oracle-to-postgres-stored-procedures` | Migrates Oracle PL/SQL stored procedures to PostgreSQL PL/pgSQL. Translates Oracle-specific syntax, preserves method signatures and type-anchored parameters, and applies `COLLATE "C"` for Oracle-compatible text sorting. |
| `migrating-oracle-to-postgres-stored-procedures` | Migrates Oracle PL/SQL stored procedures to PostgreSQL PL/pgSQL. Translates Oracle-specific syntax, preserves method signatures and type-anchored parameters, and applies explicit collation rules (`"C"` only when appropriate, locale-specific collations when required). |
| `planning-oracle-to-postgres-migration-integration-testing` | Creates an integration testing plan for .NET data access artifacts, identifying repositories, DAOs, and service layers that need validation coverage. |
| `scaffolding-oracle-to-postgres-migration-test-project` | Scaffolds an xUnit integration test project with a transaction-rollback base class and seed data manager for Oracle-to-PostgreSQL migration validation. |
| `creating-oracle-to-postgres-migration-integration-tests` | Generates DB-agnostic xUnit integration tests with deterministic seed data that validate behavior consistency across both database systems. |

The expert agent educates users throughout the migration journey:
- **Migration Concepts**: Explains Oracle→PostgreSQL differences (empty strings vs NULL, NO_DATA_FOUND exceptions, sort order, TO_CHAR conversions, type coercion strictness, REF CURSOR handling, concurrent transactions, timestamp/timezone behavior)
- **Migration Concepts**: Explains Oracle→PostgreSQL differences (empty strings vs NULL, NO_DATA_FOUND exceptions, sort/collation behavior, TO_CHAR conversions, type coercion strictness, REF CURSOR handling, UNION ALL planning caveats, materialized-view refresh needs, concurrent transactions, timestamp/timezone behavior)
- **Pitfall Reference**: Surfaces insights from migration knowledge so users understand why changes are needed
- **Best Practices**: Advises on minimizing changes, preserving logic, and ensuring schema immutability
- **Workflow Guidance**: Presents a four-phase migration workflow as a guide users can follow at their own pace

No autonomous chaining — the user controls the pace and sequence.
For database-changing actions, the expert provides scripts and explicit run instructions; the user applies DB changes.
