Prepare v1.26.0 release

[myzie]

Release prep for v1.26.0. Nothing is published by merging this — the tag and
the GitHub release come afterward.

What's in the release

Three PRs since v1.25.1:

• Preserve OpenAI message phase and close out partial streams cleanly across providers #271 — OpenAI Responses keeps the assistant message phase; OpenAI and
  OpenAI-compatible streams close their open blocks and emit terminal events
  even when the stream ends early; compaction stops stripping provider
  metadata off truncated blocks.
• deps: update wonton to v0.0.38 and refresh dependencies #270 — dependency refresh across all eleven modules (wonton v0.0.38),
  with openai-go/v3 deliberately held at v3.50.0.
• Add dangerous permission bypass flag #268 — --dangerously-skip-permissions on the experimental dive CLI.

Why 1.26.0 and not 1.25.2

v1.25.1 was a patch with no new API. This release adds a CLI flag and changes
the order of streaming events for OpenAI-shaped providers, so it takes the
minor bump.

What this PR changes

• CHANGELOG.md — [Unreleased] becomes [1.26.0] - 2026-08-22, with a fresh
  empty [Unreleased] above it.
• Eleven go.mod files — the github.com/deepnoodle-ai/dive requirement (and
  the sub-module requirements) bumped to v1.26.0. Local replace directives
  hide a stale requirement from CI but break anyone resolving the tag, which is
  why this runs before tagging.
• docs/releases/v1.26.0.md — the release notes that get posted verbatim. The
  Highlights section is the part worth reviewing.

Verification

• make check (release-notes tests, prettier, go vet, go test) — pass
• go build ./... and go test ./... in all ten sub-modules — pass
• sync_module_versions.py --check and release_notes.py --check — pass
