refactor(ado_proxy): reduce complexity of operations() in catalog.rs

[github-actions]

What was complex

operations() in src/ado_proxy/catalog.rs was a single 391-line function (flagged by clippy::too_many_lines at 391/100) building one large vec![...] literal containing every ADO proxy read-operation entry across all capability groups (Discovery, Core, Repos, Pipelines, Boards).

What changed

Split operations() into five smaller helper functions, one per Capability group:

• discovery_operations()
• core_operations()
• repos_operations()
• pipelines_operations()
• boards_operations()

operations() itself now just concatenates the five vectors in the original order:

pub fn operations() -> Vec<Operation> {
    let mut ops = discovery_operations();
    ops.extend(core_operations());
    ops.extend(repos_operations());
    ops.extend(pipelines_operations());
    ops.extend(boards_operations());
    ops
}

No Operation entries were added, removed, or reordered — this is a pure structural split with a short doc comment on each new helper.

Before / after

• Before: operations() — 391/100 lines (too_many_lines)
• After: largest remaining function is repos_operations() at 148/100; operations() itself is well below threshold

Verification

• cargo build — clean
• cargo test --bin ado-aw — 3322 passed, 0 failed, 1 ignored
• cargo clippy --all-targets --all-features — clean
• Re-ran too_many_lines lint scoped to catalog.rs — no function above 148/100 remains
