Bring the Nexus/Praxis/Hexis integration in line with MAVEN_ECOSYSTEM_ARCHITECTURE.md: - Praxis over HTTP: drop the in-process praxis.db open (praxisstore/ praxistools) and call praxisd's /api/v1/tools/* API via a new praxisClient. Honors the "no component reads another's DB" invariant (AC#12). PraxisConfig.DBPath -> URL. - Hexis confirmation gate: mutating capabilities (ReadOnly=false) now park a bound pendingHexis confirmation and require a spoken "да" before executing; read-only run immediately (AC#7, no auto attention->action). - Capability safety: >1 verb match is ambiguous -> ask instead of firing the first; ambiguous Nexus resolution asks for clarification (AC#2). - Correlation IDs on Hexis execute, recorded in the cross-service trace. - Bug: importance arrives as JSON float64 over HTTP, not int. - Tests: confirm-gate, decline, read-only, and ambiguity paths. Build: vendor/ bakes in the hexis client (replace-directed at a sibling repo outside the Docker context); Dockerfile builds from vendor and no longer `go mod download`s the unreachable replace paths.
