A read-only workspace (saves failing, a user who cannot edit, a version
preview) only hid the editing tools: plugins, the MCP among them, still
changed shapes, and those edits were never saved. Every plugin write now
throws a read-only error, whatever the throwValidationErrors flag, the
same way a write to a removed shape does.
`check-permission` with a write permission runs the new `check-writable`,
which covers most writers. Writers without a permission check (most
context methods such as create*, group, align or flatten, the z-order
methods, applyTypography on a text range, removing a ruler guide) call it
themselves, and shape setters get it through `check-shape-writable`.
Reads, comments and undo blocks keep working, so a block opened before a
lock still closes.
The MCP instructions tell the agent what the read-only error means.

The plugin text API rejected negative letter-spacing even though the
product UI allows -200..200 (typography.cljs). Two defects in
frontend/src/app/plugins/text.cljs:
- `letter-spacing-re` (`#"^\d*\.?\d*$"`) had no provision for a leading
minus, so any negative value failed validation.
- The text-range `:letterSpacing` setter inverted its guard: it used
`(or (empty? value) (re-matches ...))` to mean "invalid", which
rejected matching values and let non-numeric input through. The
text-shape setter and the sibling `lineHeight` range setter both
correctly use `(not (re-matches ...))`.
Fix the regex to allow an optional leading minus and add the missing
`not` so the range setter matches the shape setter. Adds regression
coverage for the regex accept/reject contract.
