fix(compressed-account): make light-program-profiler optional for no_std (#2394) - #2397
Fixes#2394. Makes light-program-profiler an optional dependency in light-compressed-account gated behind the profile-program and profile-heap features so default and no_std builds do not transitively pull in std.
Summary by CodeRabbit
Chores
Profiling options are now feature-gated, allowing program and heap profiling to be enabled independently in supported builds.
Profiling annotations are applied only when program profiling is enabled; default builds remain unprofiled.
The compressed-account crate now makes light-program-profiler optional. Profiling features activate the matching profiler features, and profiling attributes apply only when profile-program is enabled.
Changes: Compressed-account profiling
Layer / File(s)
Summary
Profiler dependency and feature wiring program-libs/compressed-account/Cargo.toml
light-program-profiler is optional. profile-program and profile-heap activate the matching profiler features; profile-heap also retains light-heap.
The profiler becomes optional without an established new failure. Bare-metal builds still have a pre-existing num-bigint dependency on std; fixing that and adding a dependency regression check remain follow-up work.

[#2394] light-program-profiler is optional and enabled only by the profiling features. The profiler imports and attributes are gated by profile-program, so default and no-default-feature builds do not require this dependency. No target build results were provided.

Remove num-bigint’s std dependency from the no-std path.
When profiling is disabled, light-hasher still enables num-bigint’s default std feature. Builds for targets without std therefore fail. Disable that feature on the no-std dependency path and verify the bare-metal build.

Add a profiler dependency regression check.
The host and SBF checks do not detect an unconditional profiler dependency. Add a check of the target-side dependency graph with profiling disabled. A bare-metal build check also requires fixing the existing light-hasher dependency on num-bigint with std enabled.
