   … chaining (#36)
   
   * chore(preflight): move examples/preflight.py → tools/preflight.py
   
   Preflight is a non-actuating hardware diagnostic — port discovery and
   firmware sanity check, no pipetting workflow. AGENTS.md classifies that
   as `tools/` ("hardware experiments"), not `examples/`. Moving it makes
   the categorization match the convention now that `tools/` exists.
   
   - `git mv examples/preflight.py tools/preflight.py`
   - README, docs/calibration.md, docs/hardware.md, docs/sbc-deployment.md,
     docs/marlin-commands.md updated to the new path
   - examples/showcase_v0_pipette_sim.py and tools/{diagnose_axis,marlin_repl}.py
     error messages updated
   - AGENT_LEARNINGS.md and AGENT_REQUESTS.md references updated
   - CHANGELOG: new "Changed" entry for the move; existing [Unreleased]
     entries that mention the old path updated; the `[0.0.1]` historical
     entry is left intact
   - Makefile: `tools/` added to the `ruff format/check` targets so
     `make validate` covers the whole tools/ tree
   
   PR #31 (auto-detect on examples/preflight.py) will need rebase onto
   the renamed file after this lands.

   * feat(preflight): add --export flag for shell `eval` chaining
   
   Lets the discovered ports flow directly into the next command without
   copy-paste. Probe chatter is routed to stderr in this mode; stdout
   emits only `export I3MEGA_PORT=...` / `export PIPETTE_PORT=...` lines.
   A failed discovery exits non-zero with no stdout output, so
   `eval "$(...)" && next-cmd` short-circuits cleanly.
   
   Example workflow:
   
       eval "$(uv run python tools/preflight.py --export)" \
         && uv run python examples/showcase_v0_pipette_sim.py
   
   CHANGELOG entry added under [Unreleased] / Added.
