### Why are the changes in this PR needed? The DAP debugger currently truncates variable values to a hardcoded limit of 100 characters, with no way for callers to configure it. Long values cannot be inspected or copied whole from a debugger UI. ### What are the changes in this PR? - Add a new `SetMaxVariableLength` Debugger option (in both `v1/debug` and the top-level `debug` package) - A value of 0 disables truncation; the default stays 100 characters for backward compatibility - Plumb the limit through `variableManager` and `namedVar`, so it applies to top-level and nested (object/array/set) variables alike - Relax `truncatedString` to return the original string unchanged when the limit is <= 0 - Add `TestTruncatedString` and `TestVariableValueLengthLimit` covering the default limit, unlimited (0), negative, custom limits, and boundary cases ### Notes - `go build ./...` and `go test ./v1/debug/...` both pass - Default behavior is unchanged; the new option is opt-in - This PR was developed with AI assistance (Claude Code) ### Further comments Refs #8890 --------- Signed-off-by: summy wu <summy.wu81@gmail.com>
