docs(p10-1a-2): README/HANDOFF/ARCHITECTURE/SMOKE/INDEX + HOTFIXES; chore: bump version 0.6.0 → 0.7.0

- README: note Rust .rs ingest active (code-rust-ast-v1), update Mermaid parse node + chunker labels, update supported formats note in Quick start and ingest command table; add code citation fields (symbol, code_lang, repo) and filter flags note
- HANDOFF: flip P10 row to note 1A-1 ✅ + 1A-2 PR open; add one-liner cross-link to HOTFIXES 2026-05-19 entries
- ARCHITECTURE: add kebab-parse-code node + edge (app → pcode, pcode → ptypes) to Mermaid graph; add directory tree entry; add code parser locked-in decision row (tree-sitter lives parser-side, design §6.3)
- SMOKE: add P10-1A-2 Rust code ingest section (ingest.code config keys, verification steps, known behaviors); add checklist item
- tasks/INDEX.md: flip p10-1A-1 to ✅, update p10-1A-2 to 🟡 PR open
- tasks/p10/INDEX.md: same flips
- tasks/HOTFIXES.md: add two 2026-05-19 dated entries (AST_CHUNK_MAX_LINES constant vs config deviation + SourceType::Code deferred)
- tasks/p10/p10-1a-2-rust-ast-chunker.md: append two HOTFIXES cross-link lines in Risks/notes
- docs/superpowers/specs/2026-04-27-kebab-final-form-design.md §10.1: note p10-1A-2 surface activation
- Cargo.toml: version 0.6.0 → 0.7.0 (dogfooding-ready = minor bump trigger per CLAUDE.md)
- Cargo.lock: regenerated
