docs: changelog for v0.3.0 (2026-07-27)

[cursor]

Summary

Adds CHANGELOG.md with the v0.2.0 backlog (previously drafted in open PR #45 but never merged) and a new v0.3.0 section covering merged work on main from 2026-07-26 → 2026-07-27.

Type

• Docs only

Date range analyzed

2026-07-26 → 2026-07-27 (cutoff: ac56b60 / PR #44 merge → 6495cbb / PR #47 merge)

Version bump

• Previous: 0.2.0 (drafted, not yet on main)
• New: 0.3.0
• Rationale: MINOR — new Quarto PR Progress Graph page (Add immersive PR progress node graph to Posit site #47), substantial vLLM baseline documentation and persona prompt improvements, and promotion of multi-model LLM findings into the core manuscript (Promote prompt-v1 multi-model LLM findings in core manuscript #46); no breaking API removals identified.

Categories included

• Added — persona prompt efficiency docs, vLLM baseline/memo pages, PR Progress Graph site page (Add immersive PR progress node graph to Posit site #47), APA citation style
• Changed — manuscript LLM findings promotion (Promote prompt-v1 multi-model LLM findings in core manuscript #46), persona generation refinements, Posit publish config
• Fixed — duplicate [tool.pyright] block blocking pytest (Add immersive PR progress node graph to Posit site #47)

Source PRs

• Promote prompt-v1 multi-model LLM findings in core manuscript #46 — Promote prompt-v1 multi-model LLM findings in core manuscript
• Add immersive PR progress node graph to Posit site #47 — Add immersive PR progress node graph to Posit site

Notable direct commits (no separate PR): bd4f123–c76d8ad (persona prompt efficiency, vLLM docs, publish config)

Intentionally excluded

• Open PR docs: changelog for v0.2.0 (2026-07-26) #45 content is incorporated as the v0.2.0 section (not duplicated separately)
• Notebook execution-count / formatting churn already reflected under related themes

Testing

• Docs only — no code changes
