Resolve all cspell lints

[rhennigan]

Summary

Resolves all outstanding cspell spell-check lints across the repository. Fixes are applied via the least-intrusive mechanism per case:

• Dictionary + ignore patterns — added project-specific terms (e.g. AgentTools, Chatbook, paclet, wolframscript, Sourcegraph) to the .cspell.json word list, and broadened the unicode-escape ignore regexes to cover uppercase hex and \uXXXX forms.
• Inline cspell directives — added cspell: disable/ignore comments to files containing intentional non-dictionary terms that don't belong in the global dictionary (docs, specs, notes, all client-research/*.md, a FrontEnd string asset, SubmitPaclet.wl, and two test files).
• Identifier renames — where a rename read better than a dictionary entry, renamed flagged abbreviations to full words: assocs → associations in PreferencesContent.wl, and sdir → sDir, toolopts → toolOpts, Sess → Session, rootmarker → RootMarker in the test suite. These are functionally equivalent (session IDs and temp file/dir names are arbitrary).
• Truncated word fix — restored the elided Parameters key in a sample output in Notes/generating-scripts-from-tools.md so cspell no longer flags Paramet.

Also adds ignore/ to .gitignore (private scratch dir) as unrelated housekeeping.

Notes

• The identifier renames that shifted line numbers caused the repo's pre-commit hook to re-sync the line-number references embedded in TestID strings; that accounts for the larger-than-expected line counts in the test files.
• No runtime/logic changes to product source — PreferencesContent.wl is a pure variable rename plus trailing-whitespace cleanup.

Commits

1. Ignore private scratch directory in git
2. Resolve cspell lints via dictionary words and inline ignores
3. Rename abbreviated identifiers to satisfy spell-check
4. Fix truncated word in generating-scripts-from-tools note

Test plan

• cspell reports no lints across the repo
• Wolfram Language test suite passes (renames are functionally equivalent; TestIDs auto-synced by the pre-commit hook)

Pull request overview

This PR aims to eliminate repository-wide cspell spell-check lints by updating the cspell configuration, adding targeted inline ignore/disable directives in content-heavy files, and renaming a few abbreviated identifiers (mostly in tests) to more dictionary-friendly forms.

Changes:

• Expanded .cspell.json with additional project-specific dictionary words and broadened ignore regexes for escape sequences.
• Added inline cspell directives to docs/specs/notes and a few Wolfram Language/test files to suppress intentional non-dictionary tokens.
• Renamed a handful of abbreviated identifiers and test temp-file/session naming strings to avoid spell-check flags, plus minor whitespace/comment formatting tweaks.
