- Rename milestone directory from 01_1957_perceptron to 01_1958_perceptron
- Update all references to use 1958 (publication year) for consistency
with academic citation format (rosenblatt1958perceptron)
- Changes affect: READMEs, docs, tests, milestone tracker
Rationale: Using 1958 aligns with the publication year and standard
academic citations, while 1957 was the development year.
Cherry-picked from: 28ca41582 (feature/tito-dev-validate)
- Remove pip install -e . requirement from CI workflow
- Add bin/tito wrapper script that sets PYTHONPATH and cwd
- Update preflight.py to use bin/tito instead of python -m tito.main
- Fix milestone command name (singular not plural)
- Use vars.TINYTORCH_ROOT with fallback to 'tinytorch'
The tinytorch/ package directory is generated via 'tito export' and
gitignored, so it won't exist in fresh CI clones. Changed from FAIL
to WARN since this is expected behavior in CI.
