What's Changed

fix(graph): make rebuild_symbol_index public for postcard decode (#1486): StructuralGraph::symbol_index is #[serde(skip)], so a graph deserialized directly via postcard::from_bytes has an empty index and find_symbols_all returns no seeds. GraphDiskStore::get already worked around this by calling rebuild_symbol_index() after decode, but that method was pub(crate), leaving downstream crates decoding a cached graph themselves with no way to repair it. Makes rebuild_symbol_index() public with a doc comment stating the invariant, and adds a postcard-roundtrip regression test. Fixes #1485.

docs: mark graph audits superseded and refresh roadmap (#1484): Extends docs/ROADMAP.md's MCP resource surface entry with blast-radius-bidirectional, and marks the 2026-08-03/08-26/08-27 knowledge-graph audits superseded by the PRs that implemented them (#1473, #1476, #1478, #1481).
chore(deps): update Cargo.lock to latest compatible versions (#1487): Refreshes Cargo.lock; only chacha20, cpufeatures, hyper, and lru moved to their latest semver-compatible patch versions. Lockfile-only, no Cargo.toml changes.
