JSONPath Plus selectors such as $.schema.`$ref currently fail to compile. This adds single-prefix backtick escapes for literal member selection in dot, recursive, and unquoted bracket notation, using the existing name-selector evaluator.

A trailing backtick remains part of the key. Strict RFC mode still rejects the extension, quoted keys retain literal backticks, and filters continue to use quoted bracket notation. Normalized paths use quoted brackets.

Related: daveshanley/vacuum#1004. Vacuum integration: daveshanley/vacuum#1012 (pins this exact commit).

Validation: full Go suite including the RFC compliance submodule; focused race tests; regressions fail against the base parser; new scanner has 100% statement coverage. Independent correctness and de-slop reviews found no material issues.

Risk: medium because parsing is shared by callers. The extension is enabled by default and disabled in strict RFC mode. Focused boundary and normalization tests cover the new syntax; evaluation is unchanged.

Please review the backtick member-selection change at 6f28853. All CI checks pass, including Linux, Windows, macOS, and the full compliance suite.
