Chat/agent harness work: request-authority model, turn contract, tool
policy/parsing/execution, clean_agent_preview streaming/thinking, ask_user
persistence, session probes, and scheduler.
Source: vendor/photocraft (ad1cff44) harness files, 3-way merged onto
upstream/dev (a8c147b2). Harness core files were independently developed
in both lineages; resolution policy documented in pr_work/C_conflicts.md
(vendor kept where ahead, upstream kept where vendor is behind; full delta
preserved in pr_work/C_upstream_delta.patch).

* test: align README presentation guards with the #4306 refresh
The 'Refresh README presentation' change (#4306) swapped the ASCII banner
for a centered wordmark image and moved the native quickstart into
docs/setup.md, which left four base tests failing on dev and froze the
merge gate:
- test_security_regressions::test_readme_native_quickstart_uses_loopback
now also accepts the loopback guidance from docs/setup.md, where the
quickstart moved (no behaviour change; the guidance is intact there).
- test_readme_ascii_fenced guards the new wordmark title instead of the
removed ASCII banner, and keeps a defensive check that any reintroduced
box-drawing banner stays inside a code fence (the original #1390 mode).
- The five unreferenced demo gifs under docs/ (chat, compare, document,
notes, research) are removed so test_docs_no_orphan_images passes; they
were de-referenced by the refresh. Recoverable from history if a docs
page wants to embed them again.
* chore: refresh PR checks

The decorative banner under the title wasn't in a fenced code block, so GitHub's
markdown collapsed its leading whitespace and joined the box-drawing rules,
rendering the ASCII art misaligned instead of monospace-as-typed (issue #1390).
Fence it; the H1 title stays a real heading.
