* docs: update installation guides for v0.1.5 and conda-forge feedstock status
Fixes inconsistency flagged in PR #439 review: README now says conda-forge
feedstock is available, but the linked installation guides (EN/JA) still
referenced v0.1.3 and "under review in staged-recipes".
- Update version reference v0.1.3 → v0.1.5 in both guides
- Replace "not yet available on conda-forge" with feedstock-available note
- Update Conda section language from "future native conda-forge package" to
reflect that the feedstock exists but may lag PyPI
