Add Logseq cheatsheets: syntax, queries, datalog schema

[alycda]

Why

Logseq is absent from the upstream cheat/cheatsheets repo — verified, raw.githubusercontent.com/cheat/cheatsheets/master/logseq 404s, as do datalog, datascript, and obsidian. That repo is scoped to CLI tools, so a GUI outliner was never going to land there. Good fit for our own community/ tree instead.

What

Eight sheets under tools/cheat/cheatsheets/community/logseq/, split rather than one wall of text because the layers get reached for at different times — the plaintext syntax you type all day vs. the Datalog layer you only touch when a simple query runs out of road.

sheet	contents
syntax	refs, embeds, key:: value properties, trigger chars, macros, templates, KaTeX
tasks	markers, [#A], SCHEDULED/DEADLINE, the three repeater kinds (.+ ++ +)
query	the {{query}} simple DSL, query-table::, {{function (sum :price)}}
datalog	advanced query shape, :inputs, worked examples, custom :rules
schema	:block/* attributes + built-in rule signatures
keys	default shortcuts and the :shortcuts rebinding syntax
config	config.edn keys worth knowing, :macros, :default-queries
db-version	how the DB rewrite renames all of the above

Notes

db-version is the sheet that earns its keep. Logseq's SQLite rewrite renames the entire query surface — :block/content → :block/title, :block/marker → :logseq.property/status, :block/path-refs replaced by a (has-ref) rule, (page-tags) → (tags). Every advanced query on a blog or forum post assumes the file-based names, so a copy-pasted query returns empty with no error. Cheaper to keep the rename table one cheat away than to debug it.

Content is grounded in logseq/docs at master plus the 0.10.9 source (deps/db/src/logseq/db/{schema.cljs,rules.cljc} and src/main/frontend/modules/shortcut/config.cljs) rather than recall — the rule signatures in particular are easy to get subtly wrong, e.g. (task ?b #{"TODO"}) takes a set, not a string.

README.md gains one line in the structure listing.

Testing

No Nix changes — home-manager/modules/tools/cheat.nix points at the directory, so new sheets are picked up on the next switch with nothing to wire up. Lint/check jobs are unaffected (no .nix files touched).

Worth a skim for accuracy before merge, especially the shortcut table.
