docs: rewrite README with provisioning profiles, flags, extras, and CF apps

Covers the three provisioning profiles (oem/collaborator/orchard), all
install.sh flags, the extras system (model-cache-redirect), and the full
CF apps manifest registry. The old README only described the bare PRbL
bashrc install and was stale relative to the cf-apps provisioning system.

+
+**Pyr0ball's Reductive [bash] Library (PRbL) Auto-Installer** — plus CircuitForge node provisioning.
 
 ---
 
-This installer depends on [PRbL](https://github.com/pyr0ball/PRbL-bashrc.git) and should be cloned recursively:
+Bootstraps a new machine with a sane bash environment and optionally provisions it as a CircuitForge product node or GPU worker.
+
+Depends on [PRbL](https://github.com/pyr0ball/PRbL-bashrc.git). Clone recursively:
+
+```bash
+git clone --recurse-submodules https://github.com/CircuitForgeLLC/cf-node-bootstrap.git
+cd cf-node-bootstrap/
+```
+
+---
+
+## What it installs
+
+- `PRbL` — pluggable bash functions and scripting helpers
+- A `~/.bashrc.d/` drop-in directory for modular shell config
+- An informative login splash screen (quickinfo)
+- Vim color scheme and formatting
+- Core dependencies: `git`, `vim`, `lm-sensors`, `curl`, `net-tools`, `bc`
+
+---
+
+## Install
+
+### Basic (current user)
 
 ```bash
-git clone --recurse-submodules https://github.com/pyr0ball/PRbL-bashrc.git
-cd PRbL-bashrc/
 ./install.sh -i
 ```
 
-This installer sets up a number of bash-enhancing features:
+Installs to `~/.local/share/prbl`. During install you will be prompted to:
 
-- Easy access to easy-to-use functions in bash scripting (check out ./PRbL/demo.sh for details)
+1. Install optional **extras** (e.g. dev-tool cache redirect for machines with a separate `/devl` disk)
-- A pluggable environment configuration via ~/.bashrc.d/
+2. Provision this node for **CircuitForge apps** (see Provisioning Profiles below)
-- An informative terminal login splash page
 
-Currently this installer only handles bash-like environments.
+### Global (all users, requires root)
 
-Planned features:
+```bash
+sudo ./install.sh -i
+```
 
-- Expanded automatic OS detection and package handling
+Installs to `/usr/share/prbl`.

+
+## Flags
+
+| Flag | Description |
+|------|-------------|
+| `-i` / `--install` | Install PRbL and run provisioning menus |
+| `-u` / `--update` | Update an existing install |
+| `-d` / `--dependencies` | Install package dependencies only |
+| `-D` / `--dry-run` | Show what would happen without making changes |
+| `-r` / `--remove` | Remove the PRbL install |
+| `-f` / `--force` | Remove then reinstall |
+| `-F` / `--force-remove` | Remove without reinstalling |
+| `-h` / `--help` | Print usage |
+
+---
+
+## Provisioning Profiles
+
+After the base PRbL install, the installer offers to set up CircuitForge apps on this node. You will be asked to pick a profile, which controls which apps are available and which remote they are cloned from.
+
+### OEM / customer node
+
+For end-user machines. Clones apps from the **public GitHub mirror** (`CircuitForgeLLC`). Only apps with `oem` in their `app_available_profiles` are shown.
+
+Use this for:
+- A customer deploying a licensed CircuitForge product
+- A self-hoster running a public release
+
+### Collaborator node
+
+For contributors and internal team machines. Clones apps from the **private Forgejo** instance (`git.opensourcesolarpunk.com`). All apps with `collaborator` in their `app_available_profiles` are shown, including pre-release and internal tools.
+
+Use this for:
+- A developer working on CircuitForge products
+- An internal machine with Forgejo access
+
+### Orchard-join node
+
+For GPU worker nodes joining an existing `cf-orch` orchard. Clones `circuitforge-orch` from Forgejo and hands off to its own interactive installer — when prompted, choose the `agent` topology and have your coordinator's URL ready.
+
+Use this for:
+- Adding a GPU machine to an existing CircuitForge compute cluster
+- Xander's orchard nodes or any remote worker joining a coordinator
+
+---
+
+## Optional Extras
+
+After the base install, you will be prompted to select extras. Each extra is a standalone install script in `extras/`.
+
+| Extra | Purpose |
+|-------|---------|
+| `model-cache-redirect` | Redirects pip, whisper, clip, and Hugging Face caches from `~/.cache` to `/devl/user-cache` (for machines with a separate fast disk at `/devl`). Skips cleanly on machines without a separate `/devl` mount. |
+
+---
+
+## CF Apps manifests
+
+Each CircuitForge product has a `.manifest` file under `cf-apps/`. These are plain bash files declaring the app name, description, repo URLs, supported provisioning profiles, and install types (bare-metal, Docker, Podman). See `cf-apps/README.md` for the full schema.
+
+Available apps:
+
+| App | Description |
+|-----|-------------|
+| `circuitforge-core` | Shared scaffold library required by most CF products |
+| `peregrine` | LLM-powered job discovery and application pipeline |
+| `kiwi` | Pantry tracker with barcode/receipt scanning and recipe suggestions |
+| `snipe` | Auction trust-scoring for eBay and estate sales |
+| `turnstone` | Log diagnostics tool |
+| `linnet` | Real-time tone annotation product |
+| `pagepiper` | Document/rulebook RAG tool |
+
+---
+
+## Planned
+
+- Expanded automatic OS detection and package management (non-Debian/Ubuntu)
 - Modular login splash page
