ri v0.81.3

Behavior-parity audit (constants, retry/error handling, streaming edges,
plus a live payload differential against pi), cross-implementation
interop testing against pi-written files, and the three feature gaps the
audit deferred: Copilot entitlement filtering, Bedrock/Vertex interactive
logins, and SDK-contract maxRetries.

Workspace tests: 1547 passed / 0 failed.

ri v0.81.2

Patch release: prompt-text parity with pi — typebox-exact validation
error text, pi abort checkpoints, Responses empty-text replay,
summarization truthiness and budget fallbacks, skill/template name

Workspace tests: 1471 passed / 0 failed.

ri v0.81.1

Patch release: recover truncated tool-call arguments with

Snapshot before the supplementary migration that produced v0.81.0

Last state prior to the large follow-up port: remaining six-stage plan
items, interactive OAuth, ri-owned catalog generator, SQLite lazy-read
architecture, PR #4 merge, the case-by-case pi test-parity audit
(1179 cases), and gap-closure waves 1+2.
