* fix(memory-wiki): disambiguate the reserved index page stem for synthesis and ingest
A create_synthesis or source ingest whose title slugifies to index was
written to the auto-generated <dir>/index.md. That file is the only
compiler-owned page filename: compile writes it per page group, and
compile/query/status exclude it from page scanning. So the stored fact
was both unretrievable and clobbered by the generated directory-index on
the next compile.
The collision only happens at the direct page-stem boundary: synthesis
(syntheses/<slug>.md) and ingest (sources/<slug>.md) build a bare
<dir>/<slug>.md path. The bridge, unsafe-local, and OKF callers compose
slugifyWikiSegment output into prefixed and hashed identities that can
never equal a bare index.md, and OKF already guards its own write path
via OKF_RESERVED_FILENAMES.
Add a dedicated slugifyWikiPageStem helper that escapes the reserved
index stem and route only the two direct page writers through it,
leaving slugifyWikiSegment output stable for the composed callers so
their persisted page ids and paths do not churn on upgrade. Only index
is reserved: the compiler never owns <dir>/log.md in these directories
(the wiki log lives at .openclaw-wiki/log.jsonl), so a Log title keeps
its existing direct path. Additive and deterministic, no migration.
* fix(memory-wiki): preserve reserved-page ids
