Make the docs and role prompts match the shipped modularity enforcement. The standards doc gains a Modularity section (cohesion / thin routes / thin components / god class, scan-derived + language-aware); the developer prompt tells agents to write modular code (thin routes that delegate, one concern per file, components that delegate to hooks) and that block-level findings refuse i_am_done; QA + PR-reviewer prompts note the modularity findings in evidence / the pr_pass block. Also fixes the two lifecycle diagrams (usage.md, roboco/models/README.md) that omitted the awaiting_pr_review gate.
Documentation had drifted behind the post-0.8.0 work. Adds a CHANGELOG [Unreleased] section, documents the three new feature flags in the config reference (and removes the retired ROBOCO_RAG_USE_HYDE), a new Architectural Conventions Standard page, the provider-overload break in CLAUDE.md, the >=3.13 Python floor + feature flags in the README, and the toolchain/conventions delivery gates + structured-note model across the developer / QA / PR-reviewer role docs and the task-model doc.
