## Problem
Bootstrap scripts under `provisionersdk/scripts/` are inlined into
templates via `sh -c '${init_script}'`. Any single quote (apostrophe) in
these `.sh` files silently breaks the shell quoting, causing the agent
to never start — with near-invisible error output.
## Changes
- **`scripts/check_bootstrap_quotes.sh`** — new lint script that scans
all `.sh` files under `provisionersdk/scripts/` for single quotes and
fails with a clear error if any are found. Only checks shell scripts
(not `.ps1`, which legitimately uses single quotes).
- **`Makefile`** — added `lint/bootstrap` target wired into the `lint`
dependency list.
