云微 3a722c03d5 feat: add tcx and bpf token tutorials (#203)
* feat: add tcx and bpf token tutorials

* docs: auto-generate documentation

* docs: rewrite tcx and bpf_token tutorials with richer content and consistent style

Rewrote all 4 README files (EN/ZH for both tutorials) to match the
existing tutorial style with detailed background, full code listings,
step-by-step explanations, comparison tables, and proper references.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* style: replace em dashes with colons, commas, and parentheses

* docs: auto-generate documentation

* ci: add tcx and bpf_token builds to CI; simplify execl in token_userns_demo

- Add make targets for src/50-tcx and src/features/bpf_token to the
  test-libbpf CI workflow.
- Replace four separate execl() calls with a single execv() using a
  dynamically built argv array, reducing complexity and eliminating
  CodeFactor command-injection false positives.

* ci: fix mkdocs path in trigger-sync workflow

Use .venv/bin/mkdocs instead of bare mkdocs, since make install
puts it inside a virtualenv.
