Unpin asap_sketchlib rev in workspace Cargo.toml

[milindsrivastava1997]

The workspace pins Sketchlib to a rev (Cargo.toml:17):

asap_sketchlib = { git = "https://github.com/ProjectASAP/asap_sketchlib", rev = "da3635a80f8f854d47b772d49d5a9e5fb6927d8e" }

Downstream repos (ASAPQuery-backend, ASAPCollector) depend on Sketchlib by its bare git URL. Cargo treats ?rev=… as a different source, so consumers end up with two copies of asap_sketchlib, which will cause type mismatches once Sketchlib types cross the Planner boundary.

Fix

• Use asap_sketchlib = { git = "https://github.com/ProjectASAP/asap_sketchlib" } (bare URL, no rev/branch); Cargo.lock keeps builds reproducible.
• Update Cargo.lock; fix any breakage against current Sketchlib main.
