The original CLAUDE.md described a pre-scaffolding repo with no commits and
open questions about A-2/critical path -- stale since PH0. Updates it to
point at git log as the actual status record, document the two independent
unittest discover roots (src/ and supervisor/), the real backend_server.py
CLI, the .graphlemon-worktrees/ isolation mechanism and its three real
incident notes, and a full repo layout reflecting what's actually there.

Implements c_project_create (03-C §3.0) as a plain function for U-007 to
wire up later: idempotent by target_folder_path, creates .graphlemon/ +
one init commit in an existing git repo, PATH_NOT_FOUND/PATH_NOT_WRITABLE/
GIT_INIT_DECLINED per contract, never silently `git init`s (02-V §2.1).

Also corrects a real SDD-vs-plan conflict found while scoping this Unit:
development-plan.md's U-002 line cited architecture doc §7.3's directory
tree (.claude/agents/, skills/, top-level runs/) as what to create inside
a target project. But §13.1 (a later, confirmed decision) states those are
graphlemon's own platform-repo assets (U-003 scope), and 01-M's own
graphlemon_subdir_initialized field already points at §13.2, whose target-
project tree is only .git/ + .graphlemon/ + the target's pre-existing
src/. §7.3 predates the "target project is an independent code space"
pivot and was superseded by it. Corrected development-plan.md,
unit_matrix.json, CLAUDE.md, and 05-实施约束与依赖.md accordingly (user
confirmed, 2026-07-31).

23 stdlib unittest cases (src/test_schema.py + new src/test_project_scaffold.py),
all passing.

Establishes the first commit for graphlemon before U-001 work begins:
architecture/SDD docs (including the PH5 self-hosting design already
folded into 01-M/03-C/04-P/mvcp-contract v1.7.0), the A-1 spike results,
the graphloop-adapted supervisor/isolation utilities, PH3 wireframe
prototypes (now cross-referenced from 02-V), and this session's
development-plan review (U-024 dependency split, U-035 regression
requirement, new U-004.5 e2e-harness unit, src/ directory convention).
