installation.md predated the install/packaging work that landed on main:
- drop the "once published" placeholders now that v0.2.0 is live
- fix the Homebrew/Scoop commands (tap/bucket-add forms; the bare
`brew install rdbms-playground` was wrong)
- add the curl|sh and PowerShell one-line installers (ADR-0055),
`cargo install` / `cargo binstall` (ADR-0056), and prebuilt binaries
- present winget as coming-soon (PR awaiting the public catalogue)
command-line-options.md: add `-V`/`--version` and the in-app `version`
command (ADR-0054).
Document the features the main merge shipped: `create m:n relationship`
(relationships ref + build-the-library note), the `--demo` teaching
flag (command-line-options), the Ctrl-O schema sidebar (output-pane,
now .mdx to embed the new cast), and horizontal/two-row input
(assistive-editor).
Restructure the docs into five top-level sections, splitting the
application you drive from the database language you build with.
- New "Using the playground" section: command-line options; the assistive
editor (completion, highlighting, [ERR]/[WRN] indicator, hints, in-line
editing); the output pane (scrolling); projects (save/load/new/rebuild);
undo/redo & history; export & import; clipboard; getting help. Grounded in
the in-app help/usage and ADR-0003/0022/0027.
- Reference: seed the remaining topic pages (Columns, Relationships,
Indexes, Constraints, Inserting & editing data, Querying & inspecting)
with real syntax synopses; worked examples to follow.
- Surface the assistive editor on the landing page and in Getting started;
restore cross-links now that targets exist.
Plan + STYLE updated to the five-section structure. 24 pages, build green,
links resolve, content clean; planned features carry "planned" callouts.
