setPath mutated nested sub-arrays in place; since graph-local slices (and
their nested sub-slices) may be read concurrently by other flow goroutines,
an action.array.set with a multi-level path raced readers of the same local.
The single-threaded TS source mutates in place safely, but the Go port runs
flows on concurrent goroutines, so setPath now copies on descent (every level
returns a freshly allocated slice). Adds a -race regression test that
concurrently drives nested set + inner-element reads, plus a nested-set
correctness test asserting the prior stored value is not mutated.
Found by whole-branch review (Opus); missed by the per-task reviews.

Rewrites internal/controllogic/expr.go to evaluate to Value (scalar float64
or []Value array): adds array literals [a,b], postfix indexing arr[i], and
array functions (len, sum, mean, push, pop, slice, concat, sort, …). Resolver
type changes from func(...) float64 to func(...) Value; EvalValue added;
EvalExpr/EvalBool retain scalar float64/bool returns. Three temporary shims
added in engine.go, lua.go, and expr_test.go pending Tasks 4 and 6.

Introduce server-side control-logic flow graphs (cron/alarm triggers,
Lua blocks) with CRUD endpoints, panel-logic lifecycle triggers and
user-interaction dialog nodes, and a synthetic node-graph editor.
Add an optional logic-editor allowlist (server.logic_editors) gating who
may add/edit panel logic and control logic, surfaced via /api/v1/me and
enforced in the API; hide logic affordances in the UI accordingly.
Update README, example config, and functional/technical specs to cover
all current features (plot panels, panel/control logic, local variables,
access control) and refresh the in-app manual and contextual help.
