docs: fix profile PyPI badge + flesh out root README (admin-only — org-admin write access required)

[saqlainsyed007]

Part of the cross-repo docs truth pass tracebloc/backend#962 (epic tracebloc/backend#958).

Why this is a separate issue

This is the one item of #962 that could not be landed by the assignee (@saqlainsyed007) — they have only pull permission on tracebloc/.github, so the branch cannot be pushed and no PR can be opened here.

⚠️ @LukasWodka — this one is yours alone. As the org admin you are the only person with write access to tracebloc/.github, so only you can apply and merge this change. Everyone else on the team is pull-only here.

What needs to change (two docs fixes, verified)

1. profile/README.md — the PyPI badge points at the old distribution name tracebloc-package. The canonical package is now tracebloc (the SDK's pyproject.toml declares name = "tracebloc", and it is live on PyPI at v0.16.0). Repoint the shield + link to pypi.org/project/tracebloc.
2. README.md — currently a 9-byte stub (# .github). Replace it with a real root README describing the repo (org profile, shared issue templates, reusable/caller CI workflows, CODEOWNERS, scripts/house-rules.sh).

Branch off develop, target develop (promotes to main the normal way).

Ready-to-apply patch

Save as fix.patch and git apply fix.patch from the repo root:

+Org-wide GitHub configuration for [tracebloc](https://github.com/tracebloc):
+the public org profile, shared issue templates, reusable CI/automation
+workflows, and code-ownership defaults. Files here apply across every repo in
+the org unless a repo overrides them locally.
+

+
+## What's in here
+
+| Path | Purpose |
+|------|---------|
+| `profile/README.md` | The org's public profile, rendered at [github.com/tracebloc](https://github.com/tracebloc). |
+| `.github/ISSUE_TEMPLATE/` | Shared issue forms — `bug`, `feature`, `docs`, `tech-debt` — plus `config.yml` (the template chooser; blank issues disabled, routed to Slack). |
+| `.github/workflows/` | Org-wide **reusable** workflows and their thin per-repo **caller** workflows (see below). |
+| `.github/CODEOWNERS` | Default review ownership for this repo. |
+| `scripts/house-rules.sh` | POSIX-`sh`/`awk` house-rule checker run in CI — encodes the grep-level subset of agreed team rules so they fail (or report) at commit time instead of being re-flagged one PR at a time. |
+
+## Workflows
+
+Automation is split into **reusable** workflows (the logic, `workflow_call`)
+and **caller** workflows (a few lines per consuming repo that invoke the
+reusable one). The main families:
+
+- **Kanban board automation** — `add-to-kanban`, `kanban-closure-router` / `kanban-closure-caller`, `kanban-reconcile` (weekly backstop), `kanban-archive` (daily archive of terminal items).
+- **Deploy-environment advancement** — `advance-deploy-env` / `advance-deploy-env-caller`.
+- **PR status & review gates** — `set-pr-status` / `set-pr-status-caller`, `wip-limit-check` / `wip-limit-caller`, `fr-gate` (final-review gate), `fr-pass-comment` / `fr-pass-comment-caller`.
+- **Quality** — `code-quality` (reusable), `actionlint`, `public-pii-gate`, `customer-priority-bump`.
+
+## Branching
+
+Feature work targets `develop`; `develop` is promoted to `main` via a
+`chore(promote): develop → main` PR. (Matches the org-wide convention.)
