feat: add --division flag for selective agent installation

[kienbui1995]

Closes #134

What

Adds a --division flag to install.sh so users can install agents from specific divisions only, instead of all 120 agents.

Usage

# Install only engineering agents
./scripts/install.sh --tool claude-code --division engineering

# Install multiple divisions (comma-separated)
./scripts/install.sh --tool copilot --division engineering,design

# Invalid division names are caught with helpful error
./scripts/install.sh --division invalid
# [ERR] Unknown division 'invalid'. Valid: design engineering ...

How It Works

• claude-code/copilot: Filters source directories directly
• cursor/antigravity/gemini-cli/opencode/openclaw: Builds allowed slug set from source files in filtered divisions, then matches integration filenames
• aider/windsurf: Single-file output, division filter not applicable (installs full file)
• No flag = installs all divisions (fully backward compatible)

Test Results

$ ./scripts/install.sh --tool claude-code --division engineering
  Divisions:  engineering
  Claude Code: 16 agents

$ ./scripts/install.sh --tool claude-code --division engineering,design,testing
  Divisions:  engineering design testing
  Claude Code: 32 agents

$ ./scripts/install.sh --tool copilot --division sales
  Divisions:  sales
  Copilot: 8 agents

$ ./scripts/install.sh --tool claude-code
  Claude Code: 120 agents  (no flag = all, backward compatible)

$ ./scripts/install.sh --division fake
  [ERR] Unknown division 'fake'. Valid: design engineering game-development ...

Per-division breakdown (all verified)

Total	120 ✅ matches full install

Changes

• 1 file changed: scripts/install.sh (+84 lines)
• Added --division flag parsing with validation
• Added active_divisions(), slug_allowed() filtering helpers
• Updated all 7 per-tool installers to respect division filter
• Zero changes to existing behavior when flag is not used

Hey @kienbui1995 — love this feature, it's a commonly requested one (see #134). The implementation is clean and backward-compatible.

One thing before we merge: get_field() and slugify() are duplicated from convert.sh. Could you source them from a shared location instead? A small scripts/lib.sh with the common helpers that both scripts source would keep things DRY. Something like:

# scripts/lib.sh
slugify() { ... }
get_field() { ... }
get_body() { ... }

Then both convert.sh and install.sh can . "$SCRIPT_DIR/lib.sh". Keeps maintenance simple as the helper logic evolves.

Otherwise this is good to go!

[kienbui1995]

Rebased on latest main and addressed your review feedback:

• Extracted slugify(), get_field(), and get_body() into scripts/lib.sh
• Both convert.sh and install.sh now source lib.sh instead of duplicating helpers
• Tested: convert.sh, install.sh, and install.sh --division all working correctly

Ready for re-review!

Hey @kienbui1995 — the lib.sh extraction and --division feature look solid. Two things before we can merge:

1. Missing academic division. The academic/ directory was added to main after your last rebase (commit 14cd429). It needs to be added to the ALL_DIVISIONS array and the help text's valid divisions list.

2. Merge coordination. There are a few other open PRs that touch install.sh (Add dynamic tool path detection in install.sh #216, feat: add --link flag to use symbolic links instead of copy #233, feat: install improvements - dynamic detection, Windows, cursor docs, cross-platform #327). We'll merge yours first since it's the most mature, but you'll need a fresh rebase onto current main to pick up the latest changes (including the Kimi Code integration that just landed).

Could you rebase and add academic? Once that's in, this is ready to go.
