v0.8.35

## What's new

- **CodeBuddy support** — `graphify codebuddy install` installs the skill, registers Bash + Read|Glob hooks in `.codebuddy/settings.json`, and writes the `CODEBUDDY.md` always-on section. The hooks nudge the agent toward `graphify query` instead of grepping when a graph exists. Thanks to @studyzy (#1136).
- **Fix: `--update` no longer destroys nodes** — the skill's incremental merge now passes re-extracted files to `prune_sources` so old nodes are pruned before fresh AST is inserted, preventing fuzzy dedup from collapsing distinct same-named symbols across files. A secondary guard in `dedup.py` prevents label-only merging of no-source-file nodes. Anti-shrink guard message improved (#1178).
