docs(harness+conductor): cover 5 missing styleguides in harvest; cosmetic cleanups

directive_hotswap_harness_20260627/spec.md: added the 5 missing
conductor/code_styleguides/*.md files to the harvest source list
(config_state_owner, workspace_paths, test_sandbox, chroma_cache,
code_path_audit) — the original list named 9 of 14. Added note that
the harvester should verify each contains a harvestable directive
before creating v1.md. Also verified tier2-autonomous.md path
exists (17,940 bytes) for plan Step 2.7.

tech-stack.md: removed duplicate src/paths.py entry (the full
description at line 37 already covers it; the line-73 stub was
redundant).

edit_workflow.md: Key Files section now points to src/project_files.py
for FileItem (moved out of src/models.py per the module taxonomy
refactor) and notes the line ~2748 ref may drift.

+> **Note (added 2026-07-02):** the original source list named 9 of the 14 styleguides. The 5 added here (`config_state_owner.md`, `workspace_paths.md`, `test_sandbox.md`, `chroma_cache.md`, `code_path_audit.md`) contain directive-like content that should be harvested. The harvester should verify each contains a harvestable directive before creating a `v1.md`; if a styleguide is purely descriptive (no imperative/ban/preference), skip it and note the skip in the harvest commit.
+
 **Granularity resolution:** the harvest produces a candidate list. Then the question of which directives to merge (e.g., `ban_prefix_aliasing` + `no_local_imports` might become `import_hygiene`), split, or keep standalone is resolved in the harvest phase — not locked in upfront.
