refactor(projman): extract skills and consolidate commands

Major refactoring of projman plugin architecture:

Skills Extraction (17 new files):
- Extracted reusable knowledge from commands and agents into skills/
- branch-security, dependency-management, git-workflow, input-detection
- issue-conventions, lessons-learned, mcp-tools-reference, planning-workflow
- progress-tracking, repo-validation, review-checklist, runaway-detection
- setup-workflows, sprint-approval, task-sizing, test-standards, wiki-conventions

Command Consolidation (17 → 12 commands):
- /setup: consolidates initial-setup, project-init, project-sync (--full/--quick/--sync)
- /debug: consolidates debug-report, debug-review (report/review modes)
- /test: consolidates test-check, test-gen (run/gen modes)
- /sprint-status: absorbs sprint-diagram via --diagram flag

Architecture Cleanup:
- Remove plugin-level mcp-servers/ symlinks (6 plugins)
- Remove plugin README.md files (12 files, ~2000 lines)
- Update all documentation to reflect new command structure
- Fix documentation drift in CONFIGURATION.md, COMMANDS-CHEATSHEET.md

Commands are now thin dispatchers (~20-50 lines) that reference skills.
Agents reference skills for domain knowledge instead of inline content.

-# data-platform Plugin
-
-Data engineering tools with pandas, PostgreSQL/PostGIS, and dbt integration for Claude Code.
-
-## Features
-
-- **pandas Operations**: Load, transform, and export DataFrames with persistent data_ref system
-- **PostgreSQL/PostGIS**: Database queries with connection pooling and spatial data support
-- **dbt Integration**: Build tool wrapper with pre-execution validation
-
-## Installation
-
-This plugin is part of the leo-claude-mktplace. Install via:
-
-```bash
-# From marketplace
-claude plugins install leo-claude-mktplace/data-platform
-
-# Setup MCP server venv
-cd ~/.claude/plugins/marketplaces/leo-claude-mktplace/mcp-servers/data-platform
-python -m venv .venv
-source .venv/bin/activate
-pip install -r requirements.txt
-```
-
-## Configuration
-
-### PostgreSQL (Optional)
-
-Create `~/.config/claude/postgres.env`:
-
-```env
-POSTGRES_URL=postgresql://user:password@host:5432/database
-```
-
-### dbt (Optional)
-
-Add to project `.env`:
-
-```env
-DBT_PROJECT_DIR=/path/to/dbt/project
-DBT_PROFILES_DIR=~/.dbt
-```
-
-## Commands
-
-| Command | Description |
-|---------|-------------|
-| `/initial-setup` | Interactive setup wizard for PostgreSQL and dbt configuration |
-| `/ingest` | Load data from files or database |
-| `/profile` | Generate data profile and statistics |
-| `/data-quality` | Data quality assessment with pass/warn/fail scoring |
-| `/schema` | Show database/DataFrame schema |
-| `/explain` | Explain dbt model lineage |
-| `/lineage` | Visualize data dependencies (ASCII) |
-| `/lineage-viz` | Generate Mermaid flowchart for dbt lineage |
-| `/run` | Execute dbt models |
-| `/dbt-test` | Run dbt tests with formatted results |
-
-## Agents
-
-| Agent | Description |
-|-------|-------------|
-| `data-ingestion` | Data loading and transformation specialist |
-| `data-analysis` | Exploration and profiling specialist |
-
-## data_ref System
-
-All DataFrame operations use a `data_ref` system for persistence:
-
-```
-# Load returns a reference
-read_csv("data.csv") → {"data_ref": "sales_data"}
-
-# Use reference in subsequent operations
-filter("sales_data", "amount > 100") → {"data_ref": "sales_data_filtered"}
-describe("sales_data_filtered") → {statistics}
-```
-
-## Example Workflow
-
-```
-/ingest data/sales.csv
-# → Loaded 50,000 rows as "sales_data"
-
-/profile sales_data
-# → Statistical summary, null counts, quality assessment
-
-/schema orders
-# → Column names, types, constraints
-
-/lineage fct_orders
-# → Dependency graph showing upstream/downstream models
-
-/run dim_customers
-# → Pre-validates then executes dbt model
-```
-
-## Tools Summary
-
-### pandas (14 tools)
-`read_csv`, `read_parquet`, `read_json`, `to_csv`, `to_parquet`, `describe`, `head`, `tail`, `filter`, `select`, `groupby`, `join`, `list_data`, `drop_data`
-
-### PostgreSQL (6 tools)
-`pg_connect`, `pg_query`, `pg_execute`, `pg_tables`, `pg_columns`, `pg_schemas`
-
-### PostGIS (4 tools)
-`st_tables`, `st_geometry_type`, `st_srid`, `st_extent`
-
-### dbt (8 tools)
-`dbt_parse`, `dbt_run`, `dbt_test`, `dbt_build`, `dbt_compile`, `dbt_ls`, `dbt_docs_generate`, `dbt_lineage`
-
-## Memory Management
-
-- Default limit: 100,000 rows per DataFrame
-- Configure via `DATA_PLATFORM_MAX_ROWS` environment variable
-- Use `chunk_size` parameter for large files
-- Monitor with `list_data` tool
-
-## SessionStart Hook
-
-On session start, the plugin checks PostgreSQL connectivity and displays a warning if unavailable. This is non-blocking - pandas and dbt tools remain available.
