Fixes #30740

## 维护者速读

- **改了什么**:`objectstack-data` 技能里 record 币种回填那句提示,补上 `--org
ID`(一个组织)、`--all-organizations`(写入所有组织),并说明多组织数据库两个都不带会被拒绝。
- **为什么改**:PR #30737 已把 `os migrate record-currency-codes`
改成按组织执行;技能还写着不带旗标的旧命令,AI 照做会在多组织库上直接撞拒绝。
- **风险与回滚**:只改技能文案一句,另删一句重复的话来付 token 额度;无代码改动,回滚即撤这一个 commit。
- **先看**:① `skills/objectstack-data/rules/field-types.md` 第 173-176
行的回填提示;② 同文件第 228 行删掉的那半句。
- **两分钟验证**:对照
`packages/cli/src/commands/migrate/record-currency-codes.ts` 第 92-97 行与第
130-139 行,确认两个旗标与拒绝条件与提示一致。
- **需要你做的**:批准这个 Tier H PR(`skills/**` 需人工合并)。

## What changes

- `skills/objectstack-data/rules/field-types.md`, currency-resolution
paragraph: the backfill hint now reads `os migrate record-currency-codes
--org ID` (or `--all-organizations` for every one), and says that a
multi-organization database refuses a run with neither.
- Same file, autonumber rule 2: the closing sentence "The literal
separator keeps distinct groups apart." is removed. It restated the
rule's own heading ("Put a delimiter between adjacent variable tokens"),
and removing it pays for the hint inside the token ceiling.
- `.changeset/30740-field-types-record-currency-org-flag.md`:
`'@objectstack/skills': patch`.

## Why

PR #30737 (#30674) scoped `os migrate record-currency-codes` per
organization. On `origin/main` `b3098661`,
`packages/cli/src/commands/migrate/record-currency-codes.ts` declares
`--org` and `--all-organizations` as mutually exclusive flags
(L130-139), and its header (L92-97) says a run with neither, on a
database whose rows belong to more than one organization, is refused
before any write. The skill still named the command with no flag.

## Tests

Skill prose only: no package code changed, and no eval case asserts this
hint (`git grep record-currency-codes skills/` hits only this line), so
no eval was edited.

## Acceptance notes

- **Readings (skills/\*\*).** `field-types.md`: 250 → 252 lines, 3183 →
3198 tokens (ceiling 3207, headroom 24 → 9; no ceiling raised). Bundle
(sum of every `skills/*/SKILL.md`): unchanged, 4523 lines, since no
SKILL.md is touched.
- **Out of scope, not fixed.** `content/docs/deployment/cli.mdx` L1311
still says "No flag; idempotent." for this command, while L1626 and
L1716 of the same page name `--org`. `content/docs/**` is outside this
card's file surface; reported to the seat.

## Verification

<details><summary>dispatch-gates on head f9f3cda: 42 derived, 38 run
green, 4 NOT MEASURED</summary>

`node scripts/pm/dispatch-gates.mjs --commands --repo
objectstack-ai/objectstack` derived 42 commands for the two changed
paths. 38 exited 0 on head `f9f3cda2`, including `node
scripts/check-skills-token-ratchet.mjs` (field-types.md 3198 / 3207) and
`pnpm --filter @objectstack/lint run check:doc-formula-expressions`
(after a turbo build of the `@objectstack/formula` and
`@objectstack/lint` closures, lock VERDICT command-exit 0). Four exited
3 (prerequisite not met: they read every package's built `dist/`):
`check:dts-closure`, `check:dual-build-cjs-loads`,
`check:lean-entry-closure`, `check:sourcemap-no-sources-content`. A
Markdown and changeset diff cannot move any `dist/`; a full workspace
build was not run locally, and CI's build lane is the reading of record
for those four.

`node scripts/pm/dispatch-gates.mjs --ran FILE --repo
objectstack-ai/objectstack`: "42 derived famil(ies) accounted for — 38
run, 4 NOT-MEASURED", exit 0. `pnpm lint`: exit 0.

+`skills/objectstack-data/rules/field-types.md` pointed an agent that switched a stored currency field to `'record'` at `os migrate record-currency-codes` with no flag. Since #30737 that command fills one organization's rows with `--org ID`, writes the one code into every organization only with `--all-organizations`, and refuses a run with neither on a database whose rows belong to more than one organization. The hint now says so. To stay inside the file's token ceiling, a sentence in the autonumber delimiter rule that restated the rule's own heading is removed.
