[codex] document the v0.3.2 promotion launch

[wusuiling-if]

What changed

• documented the bounded v0.3.2 promotion design and execution plan
• added a reusable launch kit with exact GitHub and Reddit copy
• recorded a machine-readable post-GitHub/pre-third-party traffic baseline with raw daily views and clones
• set the repository homepage to the v0.3.2 PyPI page
• published the canonical technical-feedback announcement in Discussion #4
• enriched the existing v0.3.2 Release notes without changing the tag or release artifacts
• published one disclosed technical post to r/LLMDevs with the Discussion flair

Promotion boundaries

• The 11/11 result is explicitly limited to the deterministic offline runtime-policy conformance suite; it is not a model-quality, provider-quality, real-world task, or SWE-bench claim.
• There is no Star/vote solicitation, automated engagement, direct-message outreach, or repeat posting.
• HN and V2EX remain human-only handoffs because their current rules prohibit generated or AI-edited submissions.
• Exactly one disclosed r/LLMDevs text post was published; it was not cross-posted, retried, reposted, or accompanied by unsolicited outreach.
