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)

fix: remove destructive cache-clear instruction from CLAUDE.md

The CLAUDE.md mandatory rule instructed clearing the plugin cache
mid-session, which breaks all MCP tools that were already loaded.
MCP tools are loaded with absolute paths to the venv, and deleting
the cache removes the venv while the session still references it.

Changes:
- CLAUDE.md: Replace "ALWAYS CLEAR CACHE" with "VERIFY AND RESTART"
- verify-hooks.sh: Change cache existence from error to info message
- DEBUGGING-CHECKLIST.md: Add section explaining cache timing

Fixes #145

fix: add cache clearing and hook verification scripts

- post-update.sh now clears plugin cache automatically
- verify-hooks.sh checks ALL locations for prompt hooks
- Prevents cached old hooks from overriding fixed hooks
