河伯 cfd89e0e28 feat(doc): warn when callout uses type= without background-color (#467)
* feat(doc): expand callout type= shorthand into background-color and border-color

When users write <callout type="warning" emoji="📝"> without an explicit
background-color, the Feishu doc renders the block with no color. This
commit adds fixCalloutType() which maps the semantic type= attribute to
the corresponding background-color/border-color pair accepted by create-doc.

- warning → light-yellow/yellow
- info/note → light-blue/blue
- tip/success/check → light-green/green
- error/danger → light-red/red
- caution → light-orange/orange
- important → light-purple/purple

Explicit background-color or border-color attributes are always preserved.
The fix is applied via prepareMarkdownForCreate() in both +create and
+update paths, and also inside fixExportedMarkdown() for round-trip fidelity.

* refactor(doc): replace silent callout type→color injection with hint output

Per reviewer feedback (SunPeiYang996), silently rewriting user Markdown is
the wrong layer for this adaptation. The type→color mapping is not part of
the Feishu spec, and covert transforms make debugging harder.

Replace fixCalloutType() (which rewrote the Markdown) with WarnCalloutType()
which leaves the Markdown unchanged and instead writes a hint line to stderr
for each callout tag that has type= but no background-color, telling the user
the recommended explicit attributes to add:

  hint: callout type="warning" has no background-color; consider: background-color="light-yellow" border-color="yellow"

Also fixes CodeRabbit feedback: the type= regex now accepts both single-quoted
and double-quoted attribute values (type='warning' and type="warning").

* fix(doc): harden background-color detection in WarnCalloutType

CodeRabbit flagged that the previous strings.Contains(attrs,
"background-color=") check missed forms like 'background-color =
"light-red"' with whitespace around the equals sign. Replace with a
regex that tolerates optional whitespace, and add a regression test.

* fix(doc): close real review gaps left over after rebase

PR #467's review thread had three substantive comments
(`fangshuyu-768`, 2026-04-21) that the prior reply messages claimed
were fixed in commit 7d4b556 — but that commit no longer exists on the
branch (lost in a rebase / squash), and the head still ships the
original buggy code. This commit makes the fixes real.

Three behavior fixes in shortcuts/doc/markdown_fix.go:

1. (#5) Tighten the type= and background-color= regex anchors. \b sits
   at any word/non-word boundary, and `-` is a non-word char, so
   `\btype=` also matched the suffix of `data-type=` — a tag like
   `<callout data-type="warning">` would emit a bogus light-yellow
   hint. Switched both regexes to `(?:^|\s)…` so a real attribute
   separator is required. The same anchor on background-color closes
   the symmetric case where a `data-background-color=` attribute
   would silently suppress the real hint.

2. (#4) WarnCalloutType is now a fence-aware line walker. Previously
   the regex ran over the entire markdown body, so a callout sample
   inside a documentation code fence (```markdown … ```) would
   generate a phantom stderr hint every time the docs mentioned the
   feature. The walker tracks fence state via the existing
   codeFenceOpenMarker / isCodeFenceClose helpers from
   docs_update_check.go, which handle both backtick and tilde fences
   per CommonMark §4.5.

3. (#3) Drop the ReplaceAllStringFunc-as-iterator pattern. The
   previous code routed callout iteration through a rewrite primitive
   whose rebuilt-string return value was discarded, then ran the same
   regex a second time inside the callback to recover the capture
   groups. New scanCalloutTagsForWarning helper uses
   FindAllStringSubmatch — one pass, no thrown-away allocation,
   intent matches the surface (read-only scan, not a mutator).

Tests: 5 new TestWarnCalloutType subtests pin each contract:

- data-type attribute does not trigger hint (#5)
- data-background-color does not suppress hint (#5, symmetric)
- callout inside backtick fence emits no hint (#4)
- callout inside tilde fence emits no hint (#4)
- callout after fence close still emits hint (#4, fence-state reset)

All 14 TestWarnCalloutType cases pass; go vet / golangci-lint
--new-from-rev=origin/main both clean.
