feat: add quick install script and packaging (#197)

Give bot-bottle a real distribution path so new users can install
without cloning the repo:

- pyproject.toml: full project metadata, a `bot-bottle` console-script
  entry point (bot_bottle.cli:main), and package-data for the runtime
  assets (Dockerfiles, egress entrypoint, netpool defaults, macos init).
  Still zero runtime pip dependencies.
- install.sh: POSIX, sudo-free, idempotent bootstrapper — checks Python
  >= 3.11, creates ~/.bot-bottle/{agents,bottles,contrib}, installs via
  pipx (pip --user fallback), then runs `bot-bottle doctor`.
- `bot-bottle doctor`: new store-free subcommand reporting Python
  version, backend availability (reuses is_backend_available rather than
  hardcoding Docker), and config-dir presence. Exits non-zero when a hard
  prerequisite is unmet.
- PRD prd-new-install-script and unit tests for doctor, the packaging
  contract, and the install script.

+# PRD prd-new: Quick install script
+
+- **Status:** Draft
+- **Author:** claude
+- **Created:** 2026-07-25
+- **Issue:** #197
+
+## Summary
+
+Add a proper Python package distribution (`pyproject.toml` with a
+`bot-bottle` entry point) plus a thin `install.sh` bootstrapper, so users
+can install bot-bottle with a single command instead of cloning the repo
+and invoking `cli.py` directly. A new `bot-bottle doctor` subcommand
+verifies host prerequisites after install.
+
+## Problem
+
+There is currently no install path for new users. The only way to run
+bot-bottle is to clone the repo and invoke `./cli.py`. This blocks any
+public demo: readers want `curl | sh` or `pipx install`, not a manual
+clone-and-configure flow. There is also no single command that tells a
+user whether their host is actually ready to run a bottle.
+
+## Goals / Success Criteria
+
+- `curl -fsSL <raw-url>/install.sh | sh` leaves a working `bot-bottle`
+  command on PATH.
+- Python-native users can install with `pipx install bot-bottle` or
+  `uv tool install bot-bottle` (once published) — or from a local
+  checkout today.
+- `install.sh` validates prerequisites (Python ≥ 3.11), creates the
+  `~/.bot-bottle/` config tree, installs the package, and runs
+  `bot-bottle doctor`. It never installs Docker or a VM backend silently
+  and never uses `sudo`.
+- `install.sh` is idempotent — safe to re-run.
+- `bot-bottle doctor` reports Python version, backend availability, and
+  config-dir presence, exiting non-zero when a hard prerequisite is unmet.
+- The package keeps **zero runtime pip dependencies** (stdlib-only,
+  matching the existing constraint in `AGENTS.md`).
+
+## Non-goals
+
+- Bundling a Python runtime or producing a standalone binary.
+- Automatic Docker / VM-backend installation.
+- Plugin-architecture changes (issue #197 floats a containerized-plugin
+  direction; that's a separate feature).
+- Publishing to a package index in this PR — the package *structure* is
+  the deliverable; publishing is a follow-up step.
+
+## Design
+
+### Package structure (`pyproject.toml`)
+
+Fill out the previously-stub `pyproject.toml` with project metadata, a
+console-script entry point, and package-data for the non-Python assets the
+runtime reads from inside the package:
+
+```toml
+[project]
+name = "bot-bottle"
+version = "0.1.0"
+requires-python = ">=3.11"
+dependencies = []
+
+[project.scripts]
+bot-bottle = "bot_bottle.cli:main"
+```
+
+`bot_bottle.cli:main` already exists (the `cli.py` shim calls it), so no
+refactor of the entry point is needed. `package-data` ships the container
+Dockerfiles, `egress_entrypoint.sh`, the firecracker netpool defaults, and
+the macos-container init script so an installed wheel can still build its
+sidecar/agent images.
+
+### `install.sh`
+
+A POSIX `sh` bootstrapper that:
+
+1. Checks `python3` is present and ≥ 3.11; exits with a clear message
+   otherwise.
+2. Creates `~/.bot-bottle/{agents,bottles,contrib}`.
+3. Installs via `pipx` if available, else `python3 -m pip install --user`.
+   The spec defaults to the git URL and is overridable via
+   `BOT_BOTTLE_INSTALL_SPEC` (used by tests / local installs).
+4. Locates the `bot-bottle` entry point (PATH or `~/.local/bin`).
+5. Runs `bot-bottle doctor` and reports the result.
+
+It is idempotent and never calls `sudo`.
+
+### `bot-bottle doctor`
+
+A new store-free subcommand (no DB migration required) that checks and
+reports:
+
+- **python** — interpreter version (hard requirement: ≥ 3.11).
+- **backend** — at least one backend available on this host
+  (macos-container / firecracker / docker), reusing
+  `is_backend_available()` rather than hardcoding Docker, since the
+  default backend is now a VM backend. Hard requirement.
+- **config** — whether `~/.bot-bottle/` exists (advisory only; `start`
+  provisions on first run).
+
+Exits 0 when both hard requirements pass, non-zero otherwise.
+
+## Testing strategy
+
+- Unit test `bot-bottle doctor` success/failure paths with backend
+  availability and Python version mocked.
+- Unit test that `pyproject.toml` parses, declares the entry point and an
+  empty `dependencies` list, and that every `package-data` glob resolves
+  to a file that exists on disk (guards against drift).
+- Unit test that `install.sh` is executable, POSIX-ish (`set -eu`), never
+  calls `sudo`, and runs `doctor` after install.
+
+## Open questions
+
+- Should `version` be derived from a git tag at build time (e.g.
+  `hatch-vcs`) or kept static? Static (`0.1.0`) is simpler for now.
+- Publishing target (PyPI vs. a self-hosted index) is deferred.
