eb85ea31bb feat(data-platform): add schema diff detection hook (#228) 
Implements PostToolUse hook to warn about potentially breaking schema changes:
- DROP COLUMN/TABLE/INDEX detection
- Column type changes (ALTER TYPE, MODIFY COLUMN)
- NOT NULL constraint additions
- RENAME operations
- ORM model field removals

Non-blocking - outputs warnings only.
Configurable via DATA_PLATFORM_SCHEMA_WARN env var.

3f79288b54 fix(data-platform): use separate hooks.json file (not inline) 
Cherry-pick fix from hotfix/data-platform-hooks to development.
Hooks must be in separate hooks/hooks.json file (auto-discovered),
NOT inline in plugin.json.

320ea6b72b fix(data-platform): correct invalid plugin.json manifest format 
- Remove invalid "agents": ["./agents/"] - agent .md files don't need registration
- Inline hooks instead of external reference "hooks/hooks.json"
- Delete orphaned hooks.json file (content now in plugin.json)

This fixes "invalid input" validation errors for hooks and agents fields.

89f0354ccc feat: add data-platform plugin (v4.0.0) 
Add new data-platform plugin for data engineering workflows with:

MCP Server (32 tools):
- pandas operations (14 tools): read_csv, read_parquet, read_json,
  to_csv, to_parquet, describe, head, tail, filter, select, groupby,
  join, list_data, drop_data
- PostgreSQL/PostGIS (10 tools): pg_connect, pg_query, pg_execute,
  pg_tables, pg_columns, pg_schemas, st_tables, st_geometry_type,
  st_srid, st_extent
- dbt integration (8 tools): dbt_parse, dbt_run, dbt_test, dbt_build,
  dbt_compile, dbt_ls, dbt_docs_generate, dbt_lineage

Plugin Features:
- Arrow IPC data_ref system for DataFrame persistence across tool calls
- Pre-execution validation for dbt with `dbt parse`
- SessionStart hook for PostgreSQL connectivity check (non-blocking)
- Hybrid configuration (system ~/.config/claude/postgres.env + project .env)
- Memory management with 100k row limit and chunking support

Commands: /initial-setup, /ingest, /profile, /schema, /explain, /lineage, /run
Agents: data-ingestion, data-analysis

Test suite: 71 tests covering config, data store, pandas, postgres, dbt tools

Addresses data workflow issues from personal-portfolio project:
- Lost data after multiple interactions (solved by Arrow IPC data_ref)
- dbt 1.9+ syntax deprecation (solved by pre-execution validation)
- Ungraceful PostgreSQL error handling (solved by SessionStart hook)
