chore: declare bench frappe/erpnext dependencies

[Guru107]

pyproject.toml had no [tool.bench.frappe-dependencies] section at all, so bench get-app / bench install-app ran no compatibility check — installing against an unsupported major would surface as a runtime failure rather than an install-time one. New modules need this declared.

[tool.bench.frappe-dependencies]
frappe = ">=15.0.0,<17.0.0"
erpnext = ">=15.0.0,<17.0.0"

erpnext is declared alongside frappe because the app hard-requires it for the Project and Item doctypes, and bench checks each entry independently — declaring only frappe would have left the ERPNext major unconstrained.

The range covers v15 and v16, matching the benches actually in use: frappe/erpnext 15.110.0 and 16.21.1.

The commented-out frappe~=15.0.0 in [project].dependencies is left as is — that is a pip dependency deliberately delegated to bench, and a separate mechanism from this section.

CLAUDE.md corrected

It claimed v15 in three places — Technology Stack (Framework, ERP) and Key Dependencies — which understated the supported range. All three now state >=15.0.0,<17.0.0, with a note that the ranges live in pyproject.toml and the two should be kept in sync.

Verification

• TOML parses; section resolves to {'frappe': '>=15.0.0,<17.0.0', 'erpnext': '>=15.0.0,<17.0.0'}
• `pre-commit run --all-files` → exit 0, including the `check toml` hook
• No Python touched
