refactor: sync agent directory lists across all scripts

[BloodShop]

Summary

The three shell scripts each maintained their own hardcoded list of agent category directories, which had drifted out of sync. This caused some agent categories to be silently skipped during linting, conversion, or installation.

Problem

Directory	convert.sh	install.sh	lint-agents.sh
academic/	✅	✅	❌ missing
sales/	✅	✅	❌ missing
strategy/	❌ missing	❌ missing	❌ missing

This means:

• lint-agents.sh never linted agents in academic/, sales/, or strategy/
• convert.sh never converted agents in strategy/
• install.sh never installed agents from strategy/

Changes

1. Add missing directories to all three scripts

All scripts now include the same 14 directories, sorted alphabetically:

academic design engineering game-development marketing paid-media
product project-management sales spatial-computing specialized
strategy support testing

2. Extract shared AGENT_DIRS constant in install.sh

Previously, install_claude_code() and install_copilot() each had their own identical inline directory list. Now both reference a single AGENT_DIRS array, matching the pattern already used by convert.sh and lint-agents.sh.

3. Sort entries alphabetically

Makes it trivial to spot missing entries when new directories are added.

Files Changed

File	Change
scripts/lint-agents.sh	Added academic, sales, strategy; sorted entries
scripts/convert.sh	Added strategy; sorted entries
scripts/install.sh	Extracted AGENT_DIRS constant; added strategy; replaced 2 inline loops

Impact

• 3 files changed, 15 insertions, 8 deletions
• Zero breaking changes — only adds previously-skipped directories
• Agents in academic/, sales/, and strategy/ will now be properly linted, converted, and installed
• Future directory additions only need updating in one place per script (the AGENT_DIRS array)

Testing

# Verify lint now picks up all dirs
./scripts/lint-agents.sh

# Verify convert processes strategy/
./scripts/convert.sh --tool cursor
ls integrations/cursor/rules/ | grep strategy

# Verify install uses shared constant
grep -n 'AGENT_DIRS' scripts/install.sh
