Compatibility / Follow-up Fixes Applied

To keep the project green on the upgraded toolchain/dependency set, additional code updates were required:

• wasmtime 41 API/macro migration in src/extensions.rs and src/pi_wasm.rs:
  • component::bindgen! async config switched to imports/exports flags.
  • linker glue updated for HasSelf generic usage.
  • new Extern::Tag variant handled.
• Event enum expansion (AgentEvent::ExtensionError) made existing matches non-exhaustive across multiple files; all affected match sites were updated.
• New clippy findings under -D warnings were fixed in tests/benches and helper code (doc markdown, float assertions, redundant clones/closures, formatting-string inlining, etc.).

Validation

Executed (with build dirs on /var/tmp due shared /dev/shm and /tmp exhaustion):

export CARGO_TARGET_DIR="/var/tmp/pi_agent_rust/${USER:-agent}/target"
export TMPDIR="/var/tmp/pi_agent_rust/${USER:-agent}/tmp"
mkdir -p "$TMPDIR"

rch exec -- cargo check --all-targets
rch exec -- cargo clippy --all-targets -- -D warnings
rch exec -- cargo fmt --check

Results:

• cargo check --all-targets ✅
• cargo clippy --all-targets -- -D warnings ✅
• cargo fmt --check ✅
