dc c7626b2797 docs(developer): a page for the browser variables, and links from where they are used
browser_info and browser_url_vars were only described inside the troubleshooting
page, under Support Diagnostics. That is the right place to find them if you
already know they exist and are looking for a log line; it is not where anyone
looks when writing a hook, which is what they are mostly for.

The new Developer Guide page carries the whole subject: which services receive
the two tables, the column lists, the debug values per platform and the MPEINIT
log lines, reading them from a hook with the exist() guard, and the reminder that
they are client-supplied and so diagnostics rather than a security boundary.

Troubleshooting keeps three stub headings - browser_info, browser_url_vars,
reading-them-from-a-hook - pointing at the page, so the anchors that are already
published keep resolving, and the detail is not maintained twice.

Linked from the three places a hook author actually starts: the HOOK Scripts
section of the MPE_TABLES page, the pre-edit hook guide (where the editor's
inputs are listed), the two-rule-sets guide (post-edit hook), and the VA embed
page, where embed=va is exactly the kind of thing a hook wants to branch on.

dc 561e92e090 docs(developer-guide): name both EDIT caps in the hook page
The truncation is whichever of DC_MAXOBS_WEBEDIT and DC_MAXCELLS_WEBEDIT
binds first, and for a wide table it is the cell cap - floor(cells/columns)
rows, potentially far below the row limit.  The hook page named only the row
cap and quoted its 250 default, so a hook author would check the row count
alone.  Same correction in the two-rule-sets page.

dc 971b007606 docs(options): the EDIT limits truncate the grid and warn
getdata no longer refuses a selection over DC_MAXOBS_WEBEDIT or
DC_MAXCELLS_WEBEDIT - it serves the rows within the limit and flags the
truncation against the table name.  Update the option reference and the two
developer-guide pages that claimed the edit screen stops with "Table is too
big".  The hook page also carried the old 500 row default.

dc 8a22e28a46 docs(developer-guide): correct the LIBREF/DS macro-scope note
The post-edit hook section claimed a `%let` "creates a new variable in the
hook's own scope and is silently discarded" while `call symputx` updates the
existing one. That is not how SAS resolves it: LIBREF and DS already exist in
an enclosing symbol table (mpe_loader's local table), and a macro only gets a
new local when the name is absent from every enclosing table, so both forms
assign to the same variable. Reworded to state that, and to keep the practical
advice (call symputx is explicit and does not depend on the enclosing scope
still holding the name).

Raised in review of #16.

dc cc91f8b1f9 docs(developer-guide): add a Developer Guide section
Two pages, both aimed at SAS developers rather than end users:

- Filter in a Pre-Edit Hook: what editors/getdata returns (sasparams.FILTER_TEXT
  and the query clauses, never FILTER_RK), when PRE_EDIT_HOOK runs relative to
  the filter, and a worked example that widens a date filter to the previous
  quarter - re-reading the table so the rows match, and keeping Row Level
  Security applied to both branches.
- One Table, Two Rule Sets: moved from the datacontroller.io blog, so the
  developer-facing material lives in one place. Images moved to docs/img/.
