Add /new-project bootstrap command (guide + wrapper)

The inverse of /retrofit: workshops a captured (new) inbox idea into a repo that is standards-compliant from line one (AGENTS.md + CLAUDE.md symlink, ROADMAP, canonical deny-by-default .gitignore, .claude wiring, inbox-check line), publishes via a manual Gitea-create gate, and clears the (new) inbox item. Resolves ROADMAP item 5 open questions (manual Gitea gate; stack quality gate deferred to /harden; workshop seeds Current state) and marks it BUILT.

+description: New-project bootstrap — workshop a captured idea into a standards-compliant repo (AGENTS.md + symlink, ROADMAP, canonical .gitignore, .claude wiring) and publish it to Gitea
+argument-hint: [optional: working name or the idea, e.g. "new:relay" or a one-line pitch]
+allowed-tools: Bash, Read, Edit, Write, Grep, Glob, Agent

+
+Bootstrap a brand-new project under `~/Projects`, standards-compliant from line one.
+Optional seed from me (may be empty): $ARGUMENTS
+
+Your complete orchestration guide — locating the inbox seed, the scope workshop, the
+sign-off gate, the scaffold layout, the Gitea publish step, and the final report — is at:
+
+    ~/Projects/standards/guides/new-project.md
+
+Read it in full first, then follow it exactly. If you cannot read that file, stop and
+report precisely that — do not improvise the bootstrap.
+
+This runs in the main thread on purpose: scoping a new project is a conversation. Ask me
+the judgment calls (the objective and non-goals, the stack, the architectural forks, the
+scaffolding-plan sign-off, and the Gitea publish) and wait — nothing lands on disk before
+Phase 3, and nothing is created without my sign-off in Phase 2. My remote is self-hosted
+Gitea, never GitHub.
