remove sales components from karen

[deepmasq]

Summary

• Remove nurturing expert, BANT scoring, deal-stage updates, crm_automation tool, shopify_cart tool from Karen
• Delete 4 sales skill directories: sales-pipeline-setup, stall-deals, stall-recovery, welcome-email-setup
• Update Karen marketplace copy (README, descriptions, tags) to reflect support-only focus

Phase 0 Steps 2+3 of Karen implementation plan. Sales components move to Sales Bot (PR #321).

What was removed

karen_prompts.py: BANT section from VERY_LIMITED, BANT scoring + deal-stage from KAREN_POST_CONVERSATION, entire KAREN_NURTURING constant

karen_install.py: nurturing expert, TOOLS_NURTURING, crm_automation + shopify_cart from tool sets, sales skills from default expert, sales-related marketplace copy

karen_bot.py: crm_automation import/tool/handler, shopify_cart tool/handler, BANT from post_conversation task title

Skills deleted: sales-pipeline-setup, stall-deals, stall-recovery, welcome-email-setup

Net: 14 insertions, 272 deletions.

Test plan

• Karen install succeeds on staging (no missing skill/prompt references)
• very_limited expert handles support questions without sales prompts leaking
• post_conversation expert logs CRM activity without BANT scoring
• Sales Bot (PR feat: Sales Bot scaffold — Phase 0 Step 1 #321) independently covers the removed functionality
