feat(cos): heal zombie issues — partial-ship hybrid + issue-reconcile task

 - **Local-model Claude agents now launch in a lean, isolated mode.** CoS agents on the Ollama-backed Claude providers (`claude-ollama`, `claude-ollama-tui`) previously inherited your full personal Claude Code environment — hooks, plugins, MCP servers, global CLAUDE.md — which reliably derailed small local models (a live eval showed qwen3.6:35b answering a session-start hook instead of its task). These sessions now spawn with `--bare --strict-mcp-config` (no hooks, no plugins, no MCP tool schemas, no CLAUDE.md auto-discovery), authenticating through the provider's existing `ANTHROPIC_BASE_URL` + `ANTHROPIC_AUTH_TOKEN` (pointed at your local Ollama), and get the same plain-`git`/`gh` completion workflow OpenCode agents use instead of slashdo commands bare mode can't load. In the same eval, once isolated this way qwen3.6:35b wrote a correct, test-passing helper (verified 46/46) end to end — the failures were the environment, not the model.
 - **Every Claude Code agent now separates its task from the PortOS operating contract.** For all Claude providers (TUI and headless CLI, local and hosted), the PortOS coordination boilerplate — worktree branch, completion-sentinel protocol, git/PR workflow — now rides in a real system prompt via `--append-system-prompt-file` (saved beside the agent's `prompt.txt` as `system-prompt.md`), while the pasted/stdin prompt carries only the task. The model weights the contract as standing instructions rather than conversation, and hosted providers get better prompt-cache reuse on the stable system block. The prompt content is byte-identical to before — only its placement changed. Codex, Antigravity, and OpenCode agents (no equivalent flag) keep the combined prompt unchanged.
 
+- **Partially-completed issues no longer become un-claimable "zombies," and a new scheduled task heals any that already exist.** When a claim run shipped only PART of an issue's scope and merged the PR, the issue was left OPEN with its `in-progress` label (and assignee) still on — and since the claim queue treats `in-progress` as "claimed and being worked," the remaining scope was never re-picked and never finished (real cases: #2220, #2179, #2175). The completion flow was binary (fully-done → close + unlabel) with no "partial ship" path, and the branch reconciler is branch-centric so it never touched the linked issue. Two fixes: **(1)** the `claim-issue` / `-gitlab` / `-jira` prompts now choose the PR trailer deliberately (`Closes` for a full ship, `Refs` + a `## Remaining` section for a partial one) and Phase 7 reconciles the issue with an agent-judged hybrid — close + file a scoped follow-up when the remainder is a clean separable chunk, else post a `Done ✓ / Remaining ▢` comment and release the `in-progress` claim so the queue re-picks it (JIRA records remaining scope + files a follow-up ticket). **(2)** a new opt-in per-app `issue-reconcile` CoS task (sibling to `branch-reconcile`, disabled by default) runs a deterministic `gh`/`git` scan for zombie issues — open + `in-progress` yet with their PR merged and no live claim anywhere (no open PR, no local/remote/CoS claim branch, no active agent) — and dispatches a coordinator agent that applies the same hybrid per issue, with an `autoClose` toggle (OFF ⇒ comment + release only) and follow-up dedup so two federated peers can't file duplicates. Perpetual drain with a convergence signature, exactly like branch-reconcile.

 ## Creative Writing Quality Engine
 
 - **[issue-2165] Editorial review now catches recognizable "AI slop" writing tells automatically.** Four new deterministic editorial checks join the existing 68: a tiered banned-word scan (hard-bans like "delve"/"myriad"/"utilize"; suspicious words like "robust"/"seamless" only flagged when 3+ cluster in one paragraph), fiction-specific AI-tell idioms ("a sense of dread", "couldn't help but", "eyes widened", "a wave of relief washed over him"), rhetorical structural tics ("not just X, but Y", runs of "did not [verb]", punchy three-sentence-in-a-row bursts like "Fast. Precise. Deadly."), and structural burstiness (em-dash overuse, essay-style transition-word openers, mechanically uniform paragraph lengths). Each surfaces as an editorial finding with the exact offending quote, same as the existing prose checks — configurable thresholds and house-style allowlists included.

+# Issue Reconcile — kill zombie issues, self-heal partial ships
+
+**Date:** 2026-07-06
+**Status:** approved → implementing
+**Related:** #2220 (closed, follow-up #2241), #2179, #2175 (released); epic tie-in with the branch-reconcile CoS task (#2237/#2240)
+
+## Problem
+
+An issue that is only PARTIALLY completed by a merged PR becomes a **zombie**:
+`OPEN` + `in-progress` label + assignee, with its PR already merged. The claim
+queue treats `in-progress` as "claimed and being worked" and skips it, so the
+remaining scope is never re-claimed and never completed.
+
+Root cause — the completion flow has no "partial completion" state:
+
+1. **`/do:next` Phase 7** (`taskPromptDefaults/prompts.js`) is *binary*: it verifies
+   the issue auto-closed via a `Closes #NUM` trailer, and if still open closes it +
+   removes `in-progress`. There is no branch for "I shipped part of the scope." The
+   only pre-ship escape (`needs-input`, `:558`) releases *without shipping*.
+2. **Branch reconciler** (`branchReconcile.js`) is entirely branch-centric — after it
+   merges an `IN_REVIEW` PR it deletes the branch/worktree but **never touches the
+   linked issue's label or state**.
+
+So a sensible partial ship with `Refs #NUM` (not `Closes`) merged via the
+reconciler/swarm path → zombie. Live examples: #2220, #2179, #2175.
+
+## Design
+
+Agent-judged **hybrid** partial-ship policy, applied in two places.
+
+### Part A — teach the completion flow "partial ship" (future direct claims)
+
+`claim-issue`, `claim-issue-gitlab`, `claim-issue-jira` Phase 5/7:
+
+- Phase 5: the PR body uses `Closes #NUM` only when the PR fully satisfies the
+  issue; a partial ship uses `Refs #NUM` + a "Remaining" section.
+- Phase 7: after merge, decide *did this PR fully satisfy the issue?*
+  - **Yes** → existing close + remove `in-progress`.
+  - **No, remainder is a clean separable chunk** → close original (comment:
+    shipped ✓ / moved to #NEW), file a scoped follow-up (`plan` + inherited area
+    labels, `Refs #orig`).
+  - **No, remainder is a continuation of the same scope** → keep open, post
+    `Done ✓ / Remaining ▢` comment, remove `in-progress` + assignee → re-claimable.
+
+Prompt-version discipline (CLAUDE.md "Distribution model"): bump `PROMPT_VERSIONS`
+for all three keys, append the outgoing bodies verbatim to
+`PREVIOUS_DEFAULT_PROMPTS`, regenerate `integrity.snapshot.json`.
+
+### Part B — new `issue-reconcile` per-app CoS task (self-heal + reconciler path)
+
+Mirrors the `branch-reconcile` shape:
+
+- **`server/services/issueReconcile.js`** (pure classifier + `gh` gatherers, unit-tested):
+  scan open + `in-progress` issues; classify each `ZOMBIE` iff a linked **merged**
+  PR references it (head ref encodes `issue-<num>`, or body mentions `#<num>`) **and**
+  there is no **live** claim (no open PR / local / remote / `cos/*/issue-<num>/*`
+  branch for it) **and** no active CoS agent. Emit a `zombieSignature` convergence
+  guard so the perpetual drain parks instead of looping.
+- **`cosTaskGenerator.js`**: deterministic pre-step + dispatch block parallel to the
+  branch-reconcile block — zombies → dispatch a coordinator agent that reads each
+  issue+PR and applies the SAME hybrid decision; none → park on `recheckCron`.
+- **Registration**: `SELF_IMPROVEMENT_TASK_TYPES`, `DEFAULT_TASK_INTERVALS`
+  (PERPETUAL, disabled, `recheckCron: '0 4 * * *'`, `taskMetadata.autoClose: true`),
+  `MANAGED_AGENT_OPTIONS` (lock `useWorktree`/`openPR` off — the coordinator works
+  over `gh`, no worktree), the task-description map, `PROMPT_VERSIONS`
+  (`issue-reconcile: 1`), `ALLOWED_TASK_METADATA_KEYS` (`autoClose`), and the new
+  coordinator prompt body.
+- **Disabled by default** → no migration needed (new opt-in task).
+- **`autoClose` toggle** (default ON): when OFF the coordinator never closes an
+  issue, only comments + unlabels — a safety valve for users who prefer one thread
+  per feature.
+
+**Peer safety** (differs from branch-reconcile, which is local-ref-only): issue
+state is shared GitHub state across federated peers (void/null/NaN/undefined).
+Close/unlabel are idempotent; the one real race is *filing a duplicate follow-up
+from two machines*, so the coordinator dedupes by searching for an existing
+follow-up (`Refs #orig` marker) before filing. v1 pre-step is `gh`-only and parks
+on non-GitHub apps; GitLab/JIRA siblings are deferred (see PLAN.md).
+
+## Part C — heal the three current zombies (done)
+
+- **#2220** — separable remainder → **closed**, follow-up **#2241** filed.
+- **#2179**, **#2175** — continuation → kept open, `Done/Remaining` comment,
+  `in-progress` + assignee removed.
