🤖 (aa-ffi-node): Bump agent-assembly git pins to v0.0.1-rc.2

[Chisanan232]

Auto-bump every agent-assembly git-SHA pin (aa-sdk-client,
aa-proto, and any other shared crate) in
native/aa-ffi-node/Cargo.toml to track agent-assembly release
v0.0.1-rc.2 (commit fc90f85d63dcf2ccffbf4f920b4f41e9bc9b1a0a).

Per ADR 0003 all aa-* git deps must share one rev so cargo resolves
a single checkout of the agent-assembly workspace; this PR bumps them
in lockstep (AAASM-3468).

Why: without this PR, the SDK source pin drifts behind the published
agent-assembly binaries (AAASM-2880 observed an 8-day drift behind
alpha-9). Merging this PR on node-sdk realigns the native shim
with the matching upstream tag.

Upstream tag: https://github.com/ai-agent-assembly/agent-assembly/releases/tag/v0.0.1-rc.2
Source workflow: https://github.com/ai-agent-assembly/agent-assembly/actions/runs/28278310685
