Add docs/README.md — OctoAcme project management overview and doc index

[Copilot]

No top-level README existed for docs/, leaving the eight process documents undiscoverable and lacking a shared context for new contributors.

Changes

• docs/README.md (new file)
  • One-paragraph intro stating the purpose of the docs directory
  • Four-paragraph overview covering: project lifecycle (initiation → planning → execution → release → close/retro), core personas (PM, PdM, Developers, QA, Stakeholders), communication cadence and escalation paths, and QA/CI/PR review practices
  • 📚 Process Docs section with relative links to all eight existing docs

Original prompt

Create a pull request to address GitHub issue #2.

Goals

1. Add a README file under docs/ that provides a brief overview of OctoAcme's project management processes.
2. The overview content should be based on the 3–4 paragraph summary previously created in this conversation, and should focus on:
   • key workflows / lifecycle (initiation → planning → execution → release → close/retro)
   • personas/roles (PM, PdM, Developers, QA/Testing, Stakeholders)
   • communication strategies / cadence and escalation
   • quality assurance practices (testing, CI, PR review, release checklists)
3. Ensure the new README fits the repo's documentation style and links to the existing process docs in docs/.

Implementation details

• Create docs/README.md.
• Include:
  • A short intro explaining the purpose of the process docs.
  • The 3–4 paragraph overview of OctoAcme project management processes.
  • A bulleted list of links to each process document in docs/ (overview, initiation, planning, execution & tracking, risks & communication, release & deployment, retrospective & continuous improvement, roles & personas).

Acceptance criteria

• docs/README.md exists and renders cleanly in GitHub.
• Overview text matches the previously produced summary and is consistent with the existing docs in docs/.
• README includes links to the existing docs.

PR metadata / issue linkage requirements

• The pull request must be linked to and added to issue README, project management processes summary, and links | Add a README for OctoAcme Project Management Docs that links all docs and summarizes processes #2.
• Request review from GitHub user zhoucengchao.
