[BUG] --target opencode still writes to .github/prompts/ and .github/agents

[tr4l]

Describe the bug

When running apm install --target opencode, APM correctly restricts skill deployment
to .opencode/skills/ but unconditionally writes prompts to .github/prompts/ and
agents to .github/agents/, creating a .github/ directory even when the user never
requested it.

To Reproduce

1. Create a fresh directory with only .opencode/ present
2. Run apm install some/package --target opencode
3. Observe .github/prompts/ and .github/agents/ created alongside .opencode/

Expected behavior

With --target opencode, only .opencode/ should be written to.
No .github/ directory should be created or modified.

Root cause (identified)

In src/apm_cli/commands/install.py, _integrate_package_primitives() runs
prompt_integrator.integrate_package_prompts() and
agent_integrator.integrate_package_agents() unconditionally. The integrate_vscode
guard is only applied to instructions and hooks, not to prompts and .github/agents/.

# No integrate_vscode guard — always writes to .github/prompts/
prompt_result = prompt_integrator.integrate_package_prompts(...)
# No integrate_vscode guard — always writes to .github/agents/
agent_result = agent_integrator.integrate_package_agents(...)
# Correctly guarded
if integrate_vscode:
    instruction_result = ...

Fix: guard both calls behind if integrate_vscode:.
Environment

• OS: Linux/WSL2
• Python Version: 3.12
• APM Version: main@b56c537cf5a23807b01ca7ea434968981bdded36

I'd say likely related to #482

Thanks for the detailed report and root-cause analysis, @tr4l -- spot on.

The core problem was that _integrate_package_primitives() ran prompt and agent integrators unconditionally, ignoring the --target gate. Your diagnosis was exactly right.

Fix: #494 replaces the entire boolean if-chain with a data-driven target x primitive dispatch loop. The loop only iterates over primitives declared by each target's profile, so --target opencode now physically cannot dispatch to .github/ -- those primitives simply don't exist in the opencode profile.

Verified locally with microsoft/apm-sample-package:

$ mkdir .opencode && apm install microsoft/apm-sample-package --target opencode
  |-- 1 agents integrated -> .opencode/agents/
  |-- 2 commands integrated -> .opencode/commands/
  |-- 1 skill(s) integrated -> .opencode/skills/

# .github/ -> not created

This will ship in v0.8.7 once #494 merges. Thanks again for filing this -- it helped us catch a broader architectural gap affecting all targets.
