feat(cli): add asset system for commands, templates, hooks, and presets

[gpolanco]

What

Extend dev-workflows from a rule compiler to a complete AI workflow system with support for commands (slash commands), templates (spec templates), hooks (editor hooks), and presets (bundles of rules + assets).

Why

Implements the spec-driven development workflow architecture. Users can now run devw init --preset spec-driven on any project and get a complete AI workflow: /spec → /plan → /build → /learn.

Changes

New files (12)

• packages/cli/src/core/assets.ts — Asset management: read, deploy (commands/templates/hooks), remove
• packages/cli/src/core/settings-merge.ts — Deep-merge JSON for hooks → .claude/settings.local.json
• packages/cli/tests/core/assets.test.ts — 17 tests for asset operations
• packages/cli/tests/core/settings-merge.test.ts — 9 tests for deep merge
• content/commands/{spec,plan,build,learn}.md — 4 slash commands for spec-driven workflow
• content/templates/feature-spec.md — Feature spec template
• content/hooks/auto-format.json — Auto-format hook (PostToolUse)
• content/presets/spec-driven.yml — Preset bundling all of the above

• core/parser.ts — Parse assets[] from config (backwards-compatible)
• utils/github.ts — Generic fetchContent() / listContentDirectory() (existing functions preserved as wrappers)
• commands/add.ts — Route command/*, template/*, hook/*, preset/* to asset flow
• commands/compile.ts — Deploy assets after bridge compilation
• commands/init.ts — --preset flag, create .dwf/assets/
• commands/remove.ts — Route asset types to asset removal
• commands/list.ts — Subcommands: assets, commands, templates, hooks

Test

pnpm test  # 271 tests pass, 0 failures

Manual verification:

devw add command/spec           # downloads slash command
devw compile                    # deploys to .claude/commands/spec.md
devw add preset/spec-driven     # installs full workflow
devw list assets                # shows installed assets
devw remove command/spec        # removes asset
devw doctor                     # all checks pass
devw init --preset spec-driven  # fresh project with full workflow
