Remove tip field from buildDraftSavedOutput's returned map and flip the
test assertions in TestBuildDraftSavedOutputIncludesReferenceOnlyWhenPresent
to require tip absence. The compose-family default envelope (+send /
+reply / +reply-all / +forward) now stays within the 3-key contract
(compose_hint / draft_id / reference) defined in tech-design v1 §4.1.5.

hintSendDraft already writes the equivalent guidance to stderr, so no
UX regression — the message reaches the user via the dedicated stderr
hint channel instead of the structured stdout envelope.

This reverts commit fe001f2.

+draft-create now always attaches a fixed draft_edit_hint to its stdout
envelope (alongside compose_hint + draft_id), guiding callers to edit
the existing draft via +draft-edit --draft-id <id> instead of re-running
+draft-create and producing duplicate drafts. The hint is single-target:
only MailDraftCreate emits it; the other 5 compose shortcuts (+send,
+reply, +reply-all, +forward, +draft-edit) keep their existing envelope
shape unchanged.

applyLintToEnvelope no longer writes lint_applied_count or
original_blocked_count. Under --show-lint-details the envelope returns
only the two Finding arrays (lint_applied[] / original_blocked[]) —
callers needing a count compute it via len(arr). The change propagates
to all 6 compose shortcuts via the shared helper.

Tests, the shortcut flag description, and the lark-mail-html /
lark-mail-lint-html reference docs are updated to match.

…tcut structs (PR 787 followup)

The 4 compose shortcuts (+send, +reply, +reply-all, +forward) were missing
the `HasFormat: true` field in their Shortcut struct literals, so cobra
parse rejected `--format json` with `unknown flag: --format`. This blocked
the JSON envelope output path (compose_hint / lint envelope) that the
verify suite exercises.

The fix mirrors the existing positive siblings in the same package
(mail_draft_create.go:43, mail_draft_edit.go:29, mail_lint_html.go:43):
add a single line `HasFormat:   true,` between `AuthTypes:` and `Flags:`
in each of the 4 Shortcut struct literals. No new manual --format flag
entry is added; the framework auto-registers --format via runner.go when
HasFormat == true.

Refs: verification_report §3.1 (fail_code_bug for INT-CLI-Send-DefaultHidesStrip-01)

+draft-edit only accepted body edits via --patch-file (set_body op),
causing "unknown flag: --body" when called the same way as +draft-create.
This adds --body as a convenience flag that translates directly into a
set_body patch op, making all mail compose shortcuts consistent.

- Add --body flag to MailDraftEdit.Flags
- In buildDraftEditPatch: if --body is set, prepend a set_body op;
  mutual-exclusion check prevents combining with --patch-file body ops
- Update patch template notes to reflect the new --body shorthand
- Existing lint pipeline (Execute loop over ops) already handles the
  new op: HTML is sanitized, envelope hides lint_applied/original_blocked
  by default unless --show-lint-details is passed

Fixes: INT-CLI-DraftEdit-DefaultHidesStrip-01 and dependent cases

Bug 1: Template HTML <li> elements with class "temp-li bullet2" or
"temp-li bullet3" were missing the "bullet1" class required by the
STYLE_LIST_ITEM_NATIVE_INLINE_APPLIED lint rule, causing 18+ warnings
in --strict mode for PersonalWeekly/TeamWeekly/Resume templates.
research--market-report.html used native <li> elements which were
fully converted to Feishu-native list format (ul/ol + li with all
required class, data-* attrs, style props and text span wrapping).

Bug 2: +send lacked --body-file flag, breaking the E2E workflow:
  +lint-html → save cleaned.html → +send --body-file ./cleaned.html
Added --body-file flag (mutually exclusive with --body) that reads
the HTML body from a file. Matches the pattern in +lint-html.

- Add class="not-doclink" to all 20 mention-chip <a id="at-user-N"> elements
  (fixes 20× STYLE_LINK_NATIVE_INLINE_APPLIED warnings in --strict mode)
- Change class="temp-li number2" → "temp-li number1 number2" on the two
  <li data-start="a|b"> sub-items in 下周工作 nested ol
  (fixes 2× STYLE_LIST_ITEM_NATIVE_INLINE_APPLIED warnings)
- Add start="1" to the outer wrapper <ol> of the nested weekly-next sub-list
  (fixes 1× STYLE_LIST_NATIVE_INLINE_APPLIED warning; ensureAttr saw start absent)

All 23 warnings eliminated; +lint-html --strict should now exit 0.
