feat(format): add case pipe for VALUE/NAME

[chhoumann]

Adds a new case:<style> pipe option to QuickAdd format syntax variables so values can be transformed inline (e.g. {{VALUE:title|case:kebab}} -> my-new-blog).

Supported styles: kebab, snake, camel, pascal, title, lower, upper, slug.

Behavior:

• Applied after the value resolves (prompt/default/reuse)
• Does not mutate stored variable values
• Unknown styles are ignored (pass-through)
• Smart casing for acronyms/brand tokens (e.g. My API Key -> myAPIKey, iOS App -> iOSApp)

UI:

• Autocomplete for |case: styles in the format syntax suggester.

Docs + tests included.

Closes #90

Summary by CodeRabbit

• New Features

  • Value casing via |case: now supports slug and per-variable case styles; suggestions appear while typing.
  • Multi-line input forcing (|type:multiline) and a |custom option to allow free input alongside choices.

• Documentation

  • Format syntax docs updated to show keyed options (label, default, type, case) and new transformation/combination rules.

• Tests

  • Added tests covering case transformations, suggestions, parsing, and related behaviors.

📝 Walkthrough

Walkthrough

Adds per-token case transformation support for VALUE and NAME tokens via a new |case: option (styles: kebab, snake, camel, pascal, title, lower, upper, slug). Implements a transform utility, parses case in value syntax, applies transformations in the formatter, and adds tests and suggester support.

Changes

Cohort / File(s)	Summary
Docs docs/docs/FormatSyntax.md	Updated syntax docs to require keyed options (e.g., `
Case transform util & tests src/utils/caseTransform.ts, src/utils/caseTransform.test.ts	New transformCase(input, style) and CaseStyle type supporting kebab, snake, camel, pascal, title, lower, upper, slug; Unicode-aware tokenization, acronym/brand handling, slug reserved-name handling; tests covering edge cases.
Value syntax parsing & tests src/utils/valueSyntax.ts, src/utils/valueSyntax.test.ts	Parse and expose new caseStyle option in VALUE_OPTION_KEYS, ParsedValueToken, ParsedOptions; anonymous value parsing updated; tests added for case: extraction.
Formatter integration & tests src/formatters/formatter.ts, src/formatters/formatter-case.test.ts	Formatter now reads caseStyle from parsed tokens and applies transformCase() during anonymous value injection, variable replacement, and YAML collection; comprehensive unit tests added for per-token casing behaviors.
Suggester & suggester tests src/gui/suggesters/formatSyntaxSuggester.ts, src/gui/suggesters/formatSyntaxSuggester.case.test.ts	Suggester now recognizes `
Constants src/constants.ts	Added VALUE_CASE_SYNTAX and VARIABLE_CASE_SYNTAX constants and integrated into existing syntax lists.
Pipe parsing helpers src/utils/pipeSyntax.ts	New helpers splitPipeParts, stripLeadingPipe, and parsePipeKeyValue to parse pipe-delimited key:value segments reliably.
Field suggestion parser src/utils/FieldSuggestionParser.ts	Switched to pipe helpers; extended FieldFilter with new keys (inline, defaultValue, defaultEmpty, defaultAlways, caseSensitive, excludeFolders/Tags/Files) and updated parsing to use key/value parsing.
Requirement tests src/preflight/RequirementCollector.test.ts	Added tests ensuring case: is not treated as a legacy default for named/unnamed VALUE tokens.
Test utilities tests/obsidian-stub.ts	Added a no-op immediate debounce helper used by tests.

Poem

🐇 With whiskers twitching, I hop through the code,
I stitch words to kebab, snake, camel on the road.
From TITLE to slug, each token I tend,
A rabbit of cases — transform and send! 🎩✨
