docs: manual-pages.md documents bm-status(1), which is not a bundled page

[FBISiri]

Environment

• basic-memory 0.23.2 (main @ 3bf2d523)
• Python 3.14.3, CentOS Linux 8

Summary

docs/manual-pages.md documents man1/ as holding bm CLI command pages and
uses bm-status(1) as its worked example in two places. No such page is
bundled, and no man1/ page documents a bm subcommand at all — the section
ships eight pages named after the note/shell-analog tools (ls, cat,
grep, ...). A reader following the docs asks for bm-status(1) and gets a miss.

Steps to reproduce

bm man list
bm man bm-status
ls src/basic_memory/man/man1/

Actual output

bm man list — every section-1 page:

apropos(1)   cat(1)   find(1)   grep(1)   head(1)   ls(1)   tail(1)   tree(1)

bm man bm-status:

No manual entry for bm-status  (try: bm man list)

ls src/basic_memory/man/man1/ confirms the same eight files; bm-status(1).md
is not among them.

Expected

Either the page exists, or the docs name a page that does. Two doc lines assert
it does:

• docs/manual-pages.md:27 — ├── man1/ # CLI commands bm(1), bm-status(1), ...
• docs/manual-pages.md:58 — ``- man1/ — bm CLI commands → `bm-status(1)```

bm(1) is likewise absent from the bundled corpus.

Notes

Section 1 is described as "user commands (ls, grep)" at
docs/manual-pages.md:41, and the bundled pages do match that Unix reading —
so the pages may be right and only the two bm-status(1) references wrong.
The mismatch is narrower than it looks: find_page
(src/basic_memory/man/__init__.py) resolves correctly for everything that
is shipped; I checked search-notes(3), search-notes.3, search-notes-3,
3/search-notes, man3/search-notes, search_notes and
man3/search-notes(3).md all resolve to search-notes(3). Only the
documented-but-absent names miss.

Possible fix

Cheapest: update docs/manual-pages.md:27 and :58 to use a page that ships
(e.g. ls(1)), matching the section-1 definition already given at line 41.

If man1/ is instead meant to cover bm subcommands, the two lines are
correct and the pages are the gap — worth saying which, since
src/basic_memory/man/ already ships basic-memory.1 and bm.1 groff
sources (at the man/ root, not under man1/) that bm man list does not
surface.

Happy to send a PR for the docs-only fix if that is the intended direction.
