planning: apply the digested interview skill text that needs an attended re-pin #5712

Refs #5569

Problem

The remaining /planning:interview skill-text changes from #5569 all sit inside sections that plugins/planning/tests/interview-defenses.test.sh digests. Re-pinning a digest is attended-only (that file's header, lines 74-76), so an unattended run cannot make these edits. This issue needs an attended session: apply the edits, review that no defense weakened, then recompute the digests in the same change.

Acceptance criteria

• B4. SKILL.md Step 2 states both re-check triggers (a resume or a queued round about to be shown; a new constraint row) and what a failed check does (a research dispatch before the user sees it, or the recommendation shown marked "not yet researched").
• B4. skills/interview/context/loop.md "Constraint ledger" says a new confirmed row re-checks every open recommendation's Checked against: line and that a changed recommendation is revised (old, new, why) before the next round is shown.
• B4. An eval case under skills/interview/evals/: a resumed ledger whose open recommendation rests on an artifact a later constraint row excludes; the run revises or marks it before asking. The case-roster digest (pin_case_set) is re-pinned.
• B3 AC2. The SKILL.md Step 1 resume branch and the loop.md Step 1 and "Incremental persistence" resume lines resolve the surface through ${CLAUDE_PLUGIN_ROOT} again (never an absolute path copied from a handoff) and run round.sh doctor --ledger <ledger> before the first resumed round. (Step 5 already says this and is not digested.)
• 22:27Z source-first default. The SKILL.md Stance per-question shape gains a Source: block before "My recommendation:": the exact text the decision rests on as a > quote, a link to its exact section, and one line on why it makes this a question; only when the question rests on text the user has not read. The Brief carries the link, not the quote.
• B1. SKILL.md:82 (write the register's open rows yourself in the same step as add-round) points at round.sh sync-ledger instead.
• B5. SKILL.md:364, SKILL.md:408 and loop.md:313 name brief=unconfirmed and say a Brief edit after Confirm needs a new restate and a fresh Confirm.
• Item 15. The SKILL.md wrap-up step reports the items a forced wrap-up skipped (the wrapup event text starts "Skipped before wrap-up:"; round.sh status already prints it).
• Item 13. loop.md:145 stops saying alternatives are numbered and names the page's labels (Rec, (a)/(b)).
• tests/interview-defenses.test.sh passes with the digests re-pinned in one change, and a reviewer confirms no defense was weakened.
• plugins/planning version bumped and a CHANGELOG entry that passes scripts/check-changelog-parity.sh.

Draft text

B4, SKILL.md Step 2, after "Keep a running constraint ledger":

Re-ground open recommendations before they are shown. On resume, and before a queued round is shown, check each open recommendation: its Basis: cites a source read this session or a constraint row, and it does not rest on an artifact the constraint ledger now excludes. A consequential one that fails gets a research dispatch before the user sees it, or is shown marked "not yet researched". When the user adds a constraint mid-interview, write the confirmed row at once and re-check every open recommendation's Checked against: line against it; revise the ones it changes and say which.

B4, loop.md "Constraint ledger", new bullet:

• Re-check: a new confirmed row re-checks every open recommendation's Checked against: line; a recommendation it changes is revised (old, new, why) before the next round is shown.

B3, resume lines: before the first resumed round, resolve the surface through ${CLAUDE_PLUGIN_ROOT} again (never an absolute path copied from a handoff) and run round.sh doctor --ledger <ledger>; it names each element the running version needs and the ledger lacks.

22:27Z, Stance per-question shape, before "My recommendation:":

Source: <the exact text the decision rests on, as a > quote> — <link to its exact section> — <one line on why that text makes this a question>
