[1.0.0] Hydrology routing

[brendancol]

1.0.0 readiness: Hydrology routing

Area: Hydrology Functions: flow_direction, flow_accumulation, flow_length, flow_path, watershed, hand, stream_order, stream_link (d8/dinf/mfd)
Source: xrspatial/hydro/

Scope

• Public surface frozen against the README feature matrix
• Dark-corner decisions resolved (see [1.0.0] Scope freeze: reconcile dark corners #2930)

Sweep clearance, no CRITICAL or HIGH (accuracy and security first)

• Accuracy /deep-sweep xrspatial/hydro
• Security
• Performance
• API consistency

Last swept: none yet

Examples

• Notebook example
• (optional) standalone script

Linked bug issues

• flow_path_dinf hangs forever on cyclic D-inf flow directions #2796 (High) flow_path_dinf hangs forever on cyclic D-inf flow directions
• Extend lazy MFD dask assembly to stream/hand modules and study the convergence phase #2885 (triage) Extend lazy MFD dask assembly to stream/hand modules and study the convergence phase
