Internal review found the two layered-extension flags landed in the SHARED
markdownToProseMirrorCanonical wrapper, which mis-covered two tools. Move the
decision to each caller by the tool's semantics.
BLOCKER 1 — createPage was NOT covered. createPage POSTs to the server
/pages/import endpoint, which imported with DEFAULTS (math + fuzzy autolink ON),
so an agent's `$x=1$` still became a formula and `www.host` still autolinked.
Add an optional `disableMarkdownExtensions` multipart field to /pages/import
(default OFF, so human file uploads keep math ON); import.controller reads it,
import.service.importPage/processMarkdown thread it into markdownToProseMirror.
MCP createPage sends it true.
BLOCKER 2 — import_page_markdown was wrongly disabled. It goes through the same
wrapper, so hardcoding parseMath:false degraded an exported `$x^2$` to literal
text on re-import, breaking the #328 lossless export→import pair. The wrapper no
longer hardcodes the flags: it takes them from the caller and DEFAULTS to the
package importer defaults (extensions ON). Callers now set them explicitly:
- updatePageMarkdown (updatePageContentRealtime) -> OFF
- patch_node/insert_node (importMarkdownFragment) -> OFF (unchanged)
- import_page_markdown -> DEFAULTS (math ON) — #328 round-trip restored
Tests: rewrite the mcp write test around the corrected per-caller semantics
(agent-write OFF, import_page_markdown DEFAULTS incl. the REAL #328 round-trip);
add a collab-backed wiring test driving client.updatePage (OFF) and
client.importPageMarkdown (DEFAULTS) end-to-end; add a createPage multipart-flag
test; add a server import.service.processMarkdown spec (flag OFF -> literal / no
autolink, default -> math ON for human uploads); reword the prosemirror-markdown
round-trip test to its package-default scope. Mutation-verified both caller
wirings (flip updatePageMarkdown -> defaults reddens the OFF wiring test; make
the wrapper default OFF reddens the #328 round-trip).
