chore(deps): drop unused dependencies and bump dirs to 6

[senamakel]

Summary

Found by the cross-repo dependency audit in tinyhumansai/openhuman#6353 (pnpm dep:audit, tinyanalyzer-driven), verified by grep against this tree at main:

• tinyagents-registry: drop tinyagents-graph — no source in the crate references it; it was only mentioned by the tracing feature forward, which now forwards to the harness alone.
• tinyagents-graph: drop reqwest, sha2, chrono — declared but never referenced (chrono only appears in a doc comment).
• tinyagents-definition: drop dev-dependency serde_json.
• tinyagents-harness: drop bytes (the word only appears in comments); bump dirs 5 → 6, which also removes thiserror 1.x and the windows-* 0.48 family from the lockfile and lets openhuman (already on dirs 6) stop compiling both.

No source changes; manifest and lockfile only.

API Or Behavior Changes

None. The tinyagents-registry/tracing feature still enables tracing in the harness; it no longer names tinyagents-graph, which the registry never depended on in code.

Tests

• cargo fmt --check
• cargo clippy --all-targets -- -D warnings (via --workspace)
• cargo clippy --all-targets --all-features -- -D warnings
• cargo build --all-targets (cargo check --workspace --all-targets)
• cargo build --all-targets --all-features (cargo check --workspace --all-targets --all-features)
• cargo test (covered by the all-features run)
• cargo test --workspace --all-features — all suites green (1061 tests in the largest crate)

Documentation

Not needed: no public surface or behaviour changed.
