chore: upgrade inquirerer/create-gen-app and add init welcome messages

[pyramation]

Summary

Upgrades inquirerer to 2.3.0 and create-gen-app to 0.6.2 across all packages that use them. These updates include the keypress event duplication fix from constructive-io/dev-utils#29.

Dependency Changes:

• packages/csv-to-pg: inquirerer ^2.0.3 → ^2.3.0
• packages/cli: inquirerer ^2.2.0 → ^2.3.0
• pgpm/cli: inquirerer ^2.2.0 → ^2.3.0, create-gen-app ^0.6.0 → ^0.6.2
• pgpm/core: create-gen-app ^0.6.0 → ^0.6.2

Output Simplification:
Replaced @pgpmjs/logger with plain process.stdout.write / process.stderr.write in scaffold and cache commands to keep testing cleaner:

• pgpm/cli/src/commands/init/module.ts - simplified to plain stdout/stderr for init success/error messages
• pgpm/cli/src/commands/cache.ts - simplified to plain stdout for cache clear message

This removes the [scope] SUCCESS: / [scope] ERROR: prefixes and ANSI color codes from these commands.

Init Welcome Messages (Workspace & Module):
After scaffolding completes, both workspace and module init now display a friendly welcome message:

• Checks for .motd file in the created folder - if found, prints its contents and deletes the file
• If no .motd exists, prints default ASCII art:

                   |              _   _
       ===         |.===.        '\-//`
      (o o)        {}o o{}        (o o)
  ooO--(_)--Ooo-ooO--(_)--Ooo-ooO--(_)--Ooo-
  

• Prints ✨ Enjoy! followed by cd ./<folder-name> to guide the user

For module init, the cd path is calculated based on context:

• At workspace root: cd ./packages/<module-name>
• In packages/ directory: cd ./<module-name>

Snapshot Update:
Updated packages/cli/__tests__/__snapshots__/cli.test.ts.snap to reflect inquirerer 2.3.0's new prompt format. The prompt changed from multi-line format to a more compact single-line format:

• Old: autocompleteField?\nArgument --autocompleteField type [autocomplete]\n> Your input:\n$
• New: autocompleteField? (--autocompleteField)\n>

Review & Testing Checklist for Human

• Verify new inquirerer prompt format is acceptable - The prompt format changed significantly in 2.3.0 (see snapshot diff). Run any interactive CLI command and confirm the new compact prompt style is acceptable UX.
• Verify ASCII art renders correctly - Run both pgpm init workspace and pgpm init (module) and confirm the ASCII art displays with proper spacing and alignment (especially the backslash characters `'-//``)
• Test module init cd path - Verify cd instruction shows correct path when running from workspace root (packages/<name>) vs from packages/ directory (<name>)
• Test .motd file support - Create a template with a .motd file and verify it gets printed and deleted (not left on disk)

Recommended test plan:

1. Run pgpm init workspace - should show ASCII art, "✨ Enjoy!", and cd ./<workspace-name>
2. Run pgpm init from workspace root - should show ASCII art and cd ./packages/<module-name>
3. Run cd packages && pgpm init - should show ASCII art and cd ./<module-name>
4. Run pgpm init outside a workspace - should show error message via stderr
5. Run pgpm cache clean - should show "Cleared template cache for pgpm."
6. Test any autocomplete/checkbox prompt to verify the new prompt format works correctly
