feat(setup): optional bootstrap-ai.sh to install Ollama + pull a model
Keeps bootstrap.sh AI-free by default; bootstrap-ai.sh layers on the local model runtime (transparent, opt-in install) for the /ai agent. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# bootstrap-ai.sh — optional AI layer for hack-house (Ollama, local-first)
|
||||
#
|
||||
# Runs the baseline ./bootstrap.sh first, then sets up everything the /ai agent
|
||||
# bridge needs to run a LOCAL model: installs Ollama (if missing) and pulls a
|
||||
# default model. Cloud providers (anthropic / openai) need no install — just an
|
||||
# API key in the agent's env — so this script only handles the local default.
|
||||
#
|
||||
# The baseline is untouched: ./bootstrap.sh alone never installs or enables AI.
|
||||
#
|
||||
# usage:
|
||||
# ./bootstrap-ai.sh # baseline setup + Ollama + default model
|
||||
# ./bootstrap-ai.sh --release # ...and build the client in release mode
|
||||
# ./bootstrap-ai.sh --check # report only; install/pull nothing
|
||||
# ./bootstrap-ai.sh --yes # don't prompt before installing Ollama
|
||||
# ./bootstrap-ai.sh -h | --help # this help

# HH_AI_MODEL model to pull (default: qwen2.5:3b)
