feat(inlay-hints): add configurable parameter name hints

Adds configurable inlay hints for TCL procedures and merges signatures from built-ins and workspace files. The feature supports parameterNames and suppressWhenArgumentMatchesName and respects an optional range filter and current-file priority.

- Introduces built-in and custom inlay hint builders
- Honors inlayHints parameterNames and suppression options
- Adds tests validating hints, ranges, and priority rules
