iter docs-honesty-lint.1: canonical docs present-tense-honest + wrap-robust pin + Sweep 5

Strips Wunschdenken (forward intent stated as fact) and non-citation
post-mortem / doc-archaeology from docs/DESIGN.md (14 corrections incl.
1 Step-14 procedural-catch-all site the spec's illustrative regex would
have missed) + docs/PROSE_ROUNDTRIP.md; genuine forward intent (LLM
tool-use / MCP / LSP) relocated to roadmap P3. Codifies the
tense+modality discriminator as a present-tense DESIGN.md meta-
subsection. Guards two ways: wrap-robust enumerated absent/present pin
(crates/ailang-core/tests/docs_honesty_pin.rs, norm() whitespace-
collapse helper — structurally discharges the recurring grep/contains
line-wrap failure family) + wrap-robust advisory Sweep 5 in
architect_sweeps.sh (contiguous-fragment regex) with full sweep-count
lockstep + new ailang-architect.md "DESIGN.md honesty drift" bullet.
KEEPs preserved (Diverge-reserved, regions-rejected, self-labelled
tiebreaker). No language/checker/codegen/runtime change — sole crates/
change is the additive pin; ail check/run/build byte-unchanged.
Workspace 609/0 (delta +4 pin), sentinel trio green, build clean.
