warn on unknown solver and fall back to FBDF

[1-Bart-1]

Instead of throwing an error when an unknown solver is specified (e.g. DFBDF from default KiteUtils settings), emit a warning and fall back to FBDF.

Fixes #156

@claude add Readme code to test/test_setup.sh. Also the 2plate kite example in the README now doesn't run

using SymbolicAWEModels
SymbolicAWEModels.init_module(; force=false)

which will cause it to fail.

Changes pushed

• Read README and test/test_setup.sh to understand current state
• Fix README 2plate kite example: add SymbolicAWEModels.init_module(; force=false)
• Fix README pendulum example: add init_module(; force=false) + set_data_path("data/base") (also broken — Settings("system.yaml") needs an explicit data path)
• Add README pendulum code test to test/test_setup.sh
• Add README 2plate kite code test to test/test_setup.sh
• Commit and push changes

Summary

README.md — two code blocks fixed:

1. Pendulum example: added SymbolicAWEModels.init_module(; force=false) and set_data_path("data/base") — without these, Settings("system.yaml") had no valid yaml to load on a fresh install.
2. 2-Plate kite example: added SymbolicAWEModels.init_module(; force=false) right after the using line, as requested.

test/test_setup.sh — two new test blocks appended (after the existing example runs):

• README pendulum example — runs the exact README pendulum code inline in a fresh Julia process
• README 2plate kite example — runs the exact README 2plate kite code inline in a fresh Julia process

Both tests benefit from the existing init_module() call earlier in the script (which copies data into the temp dir), so subsequent Julia processes see the data directory and __init__() sets the data path automatically.
