Add a Radius Jewel Finder

[mcagnion]

Description of the problem being solved:

Finding a good socket for a radius jewel currently means manually comparing each socket, its passive radius, and the effect on the build.

This adds Find Radius Jewel to the Tree tab. Select a jewel family—or All jewels—and PoB ranks the supported jewel and socket combinations against the chosen stat. Results can be previewed and applied directly to the build.

Use the panel to select the jewel family and comparison stat, then run the calculation. The result list shows the gain, percentage gain and gain per passive point; selecting a row shows the affected socket, passives and any Foulborn mutation.

The finder can restrict searches to free sockets, safely replace ordinary occupied jewels, or consider all occupied sockets. Replacement details identify the existing jewel, while position-sensitive jewels are excluded from Safe occupied mode. Full replacement evaluation also handles cluster-tree and Timeless Jewel state safely.

The finder covers the radius jewels it can evaluate generically, including applicable Foulborn variants. Timeless Jewels continue to use their dedicated finder; conversion jewels such as Cold Steel and Fireborn are outside this tool's scope. Foulborn Might of the Meek is not included until its radius is modeled.

Steps taken to verify a working solution:

• Ran the complete automated test suite and focused system coverage for jewel data, variants, result ranking, Foulborn transformations, occupancy modes, replacement safety and popup interactions.
• Manually tested Full DPS ranking using the All jewels view.
• Verified normal and Foulborn results show the expected mutation, socket and replacement details.

Technical notes for reviewers

• RadiusJewelData owns the supported jewel catalogue and variant construction. RadiusJewelCompute owns socket evaluation, replacement handling and disconnected-passive planning. Popup workflows are separated from construction, while result, detail and tooltip controls are dedicated class modules.
• Comparison calculations preserve the live build by evaluating candidates against copied passive-tree state and restoring socket, item and allocation state after each operation. Position-sensitive, Cluster and Timeless-style replacements rebuild only the tree structures that can affect the result.
• Fast evaluation shares calculations between structurally equivalent sockets, while simulated planning enriches only the candidates that need full path details. Result rows retain compact scalar snapshots for comparison tooltips instead of build-state object graphs.
