* fix(bmad-init): correctly resolve output_folder paths outside project root
When output_folder was set to an absolute path (e.g. /Users/me/outputs),
the {project-root}/{value} result template stored it as
{project-root}//absolute/path. resolve_project_root_placeholder then did
a naive string replace, producing /project//absolute/path — a broken path
that workflows could not resolve.
For relative paths outside the root (e.g. ../../sibling), the same naive
replace left un-normalized paths like /project/../../sibling in the
resolved config, which some tools mishandled.
Fix resolve_project_root_placeholder to strip the {project-root} token,
detect whether the remainder is absolute (returning it directly) or
relative (joining with project root and normalizing via os.path.normpath).
Fix apply_result_template to skip the template entirely when raw_value is
already an absolute path, and to normalize the result for relative-but-
outside paths. This covers the bmad-init SKILL write path, which bakes
the resolved path directly into config.yaml.
Add 7 tests covering all three path cases (absolute, relative-with-
traversal, normal in-project) for both functions.
