feat: add altimate-dbt CLI and consolidate dbt skills into 5 focused skills

[suryaiyer95]

Summary

• Adds altimate-dbt CLI package (packages/dbt-tools/) — a Bun TypeScript wrapper around @altimateai/dbt-integration for dbt project operations
• Consolidates 8 scattered dbt skills into 5 focused skills with references/ directories for progressive context disclosure
• All skills now use altimate-dbt commands instead of raw dbt

altimate-dbt CLI (packages/dbt-tools/)

New package providing 16 commands for dbt project operations:

Command	Purpose
init	Auto-detect dbt project, write config
doctor	Validate project health
info	Project metadata
compile / compile-query	Jinja compilation
build / run / test / build-project	Model execution
execute	SQL execution against warehouse
columns / columns-source / column-values	Column introspection
children / parents	DAG navigation
deps / add-packages	Package management

Architecture: one-shot CLI (run command → print JSON → exit). No MCP, no server, no API key required. Wraps @altimateai/dbt-integration via DBTProjectIntegrationAdapter.

dbt Skills Consolidation

New Skill	Purpose	References	Replaces
dbt-develop	Model creation hub	6 refs	model-scaffold, yaml-config, medallion-patterns, incremental-logic, dbt-cli
dbt-test	Schema + unit + custom tests	4 refs	generate-tests
dbt-docs	Model documentation	2 refs	(enhanced)
dbt-troubleshoot	Error diagnosis workflow	4 refs	(new)
dbt-analyze	Downstream impact analysis	2 refs	impact-analysis

Deleted: dbt-cli, model-scaffold, generate-tests, yaml-config, incremental-logic, medallion-patterns, impact-analysis

Architecture: Lean SKILL.md for AI routing → deep references/ files loaded on-demand. Adopts patterns from dbt-labs/dbt-agent-skills: Iron Rules, Common Mistakes tables, explicit boundaries.

Test plan

• bun packages/dbt-tools/src/index.ts prints usage
• bun packages/dbt-tools/src/index.ts init detects dbt project
• bun test --cwd packages/dbt-tools passes
• Skills activate for correct prompt types
• Deleted skills no longer appear in skill list
• Spider2-DBT benchmark tasks for end-to-end validation
