Tianyi Cui a8986c2c8a Merge remote-tracking branch 'origin/master' into worktree-dynamic-workflows
Beyond the mechanical conflicts (provider capability lines vs master's new
inheritsParentContext field; generated catalogs regenerated rather than
hand-merged; knip/lockfile), three master-side reworks required semantic
adaptation of this branch:

- The persona rework removed AgentOptions.systemPrompt, which was the
  structured-output instruction's channel. The instruction now rides the
  SAME final-request enforcement listener that injects the schema'd tool:
  appended per request to final.system (per-request wire state, not agent
  prompt state). Tests assert the wire request (adapter.requests) instead
  of child.options; the bare-direct-dispatch test pins the no-system arm.
- Tool guidance moved out of deployment prompts into per-tool prompt
  sections; the examples' workflow paragraph became a tool:<toolName>
  section contributed by dsh-tool-workflow (explicit-ask-only policy),
  and both example personas resolve to master's minimal identity+behavior
  form. tool-workflow gains inject: systemPrompt (+ peer dep, tsconfig
  ref); the export-shape guard updated.
- The uniform-RFC-format gate: the dynamic-workflows RFC restructured to
  the implemented/ skeleton (bare Status line; Proposal -> Decision;
  What-was-rejected -> Alternatives considered; new Consequences), and
  the overall-run-timeout deferral is now recorded in the RFC's Deferred
  list. The doc-graphs atlas classification gains the workflows seam
  (workflow-vm implementation, tool-workflow consumer).

Master's harness-identity section made "empty assembled prompt" states
unreachable through the loop, so the instruction-append is a plain
undefined-ternary and the structured tests assert append-not-replace.
All snapshot goldens (including workflow-run) replay unchanged. Full
local CI-equivalent gate sequence green on the merged tree.
