* feat(telemetry): add build-time option to compile out telemetry
Gate anonymous telemetry emission behind a default-on `telemetry` Cargo
feature in openshell-core. The data model (enums, validation, emit_*/enabled*
signatures) stays always-compiled, while the endpoint, HTTP client, queue, and
emission code are feature-gated. With the feature off, enabled() returns false
and emit_* are no-ops, so dependent crates compile unchanged and no telemetry
endpoint, HTTP client, or emission code is included in the binary.
chrono and reqwest become optional dependencies of openshell-core, dropped from
its dependency graph when telemetry is disabled.
Thread the switch through the workspace: every crate depends on openshell-core
with default-features = false, and the default-on `telemetry` passthrough lives
on the binary crates that emit or collect telemetry (openshell-server,
openshell-sandbox, openshell-driver-vm). In-process drivers inherit it via
resolver v2 feature unification.
Build a telemetry-free binary with, e.g.:
cargo build --release -p openshell-server --no-default-features
The runtime OPENSHELL_TELEMETRY_ENABLED switch is unchanged for default builds.

* ci(telemetry): guard that telemetry can be compiled out
Add tasks/scripts/verify-telemetry-compiled-out.sh, which inspects a built
binary for telemetry markers (the telemetry endpoint host and client ID) that
exist only when emission code is compiled in. The rust:verify:telemetry-off
mise task builds the gateway with default features (positive control: markers
must be present, so the absent checks can never be silently vacuous) and with
--no-default-features (markers must be absent), and checks the
--no-default-features sandbox binary as well.
Wire the task into the Rust branch-checks job so a regression that reintroduces
telemetry code into a --no-default-features build fails CI.
