Replace the old Lisp-like array expression representation (["AND", ["PARAM", ...], ...]) with a class hierarchy rooted in an abstract Expression class (Literal, Parameter, Binary, Unary, FunctionCall, Conditional). This gives compile-time type safety to expression construction, evaluation, and pattern matching. Key changes: - New lib/common/expression.ts defines the class hierarchy with map/evaluate/toString methods - Rewrite parser as hand-rolled recursive descent, removing the parsimmon dependency - Extend Path with a colon separator to unify parameter identity and attributes into a single address space (e.g. "Device.WiFi.SSID.1.Name:writable"). The colon field tracks how many trailing segments are attribute qualifiers. PathSet rewritten with separate param/attr segment indexes - Flatten device attribute representation in the UI to colon-delimited keys mirroring the new path syntax
