require non-whitespace adjacency for inline formatting delimiters

An opening delimiter must now be followed by a non-whitespace character,
and a closing delimiter must be preceded by one. Empty delimiter pairs
(****, ____, '''', , , <del></del>) no longer
match and stay literal.

Rationale: this matches Markdown's flanking-delimiter
rules and eliminates accidental bolding of sequences like `** note**`
at the start of a sentence. Well-formed uses (**bold**, //italic//,
__underline__) are unchanged.

Affected modes: Strong, Emphasis, Underline, Monospace, Subscript,
Superscript, Deleted.

BREAKING: content that was already malformed but
previously rendered as formatted (e.g. `**foo bar **`) now stays
literal.

prevent inline formatting from matching across paragraph boundaries

The Lexer compiles all patterns with the `s` (DOTALL) flag via
ParallelRegex::getPerlMatchingFlags(), which makes `.` match newlines.
Inline formatting modes use lookaheads like `\*\*(?=.*\*\*)` to verify
a closing delimiter exists, so with DOTALL a lone `**` happily matched
its "closer" many paragraphs later, swallowing blank lines into a
single <strong> run.

Add CONTENT_UNTIL_PARA on AbstractMode — a regex snippet matching any
character unless it would start a paragraph break (blank line, possibly
with horizontal whitespace). Update all inline formatting entry patterns
(Strong, Emphasis, Underline, Monospace, Subscript, Superscript,
Deleted) to use it in their closing-delimiter lookaheads.

Emphasis also gets a real closing-`//` check; its previous lookahead
just verified "content exists with a non-colon char" without requiring
the closing delimiter at all.

Single newlines inside a delimiter pair still match (multi-line
formatting); only blank lines end it.

BREAKING: This means you no longer can mark multiple paragraphs as bold
or strike them out. On the other hand it prevents accidentally breaking
the page layout by missing a closing delimiter (as reported many many
times over the years) eg. #1025 #3588 #1056

add $conf['syntax'] setting and conditional mode loading in ModeRegistry

Introduce a new 'syntax' configuration setting (dokuwiki, markdown, dw+md, md+dw)
that controls which parser modes are loaded. Built-in modes are split into
always-loaded (no Markdown equivalent), DW-only, and MD-only groups.
Refactor getModes() into focused sub-methods for each group.

No Gfm mode classes exist yet, so only 'dokuwiki' is functional.
The change is a strict no-op for existing behavior.

Move old-style parser tests from _test/tests/inc/parser/ to namespaced
test classes under _test/tests/Parsing/ParserMode/ and

- Add ParserTestBase with assertCalls() helper for comparing handler
call sequences with byte index stripping
- Split lexer.test.php into ParallelRegexTest, StateStackTest, and
LexerTest with a RecordingHandler that extends Handler
- Merge handler_parse_highlight_options tests into CodeTest
- Add new tests for previously untested modes: Nocache, Notoc, Rss,
and all individual formatting modes (Strong, Emphasis, etc.)
- Modernize test code: [] syntax, lowercase null, correct assertEquals
argument order, replace deprecated withConsecutive and string callables

move handler methods into ParserMode classes and rename Handler

Each ParserMode class now implements handle() from ModeInterface,
containing the token handling logic that previously lived as individual
methods on Doku_Handler.

The Handler class (formerly Doku_Handler) is the single dispatch point:
Lexer passes tokens to Handler::handleToken() which routes to mode
objects, plugins, or returns false. The Lexer only tokenizes and
resolves mapHandler aliases.

Key changes:
- Add handle() to ModeInterface, implemented by all mode classes
- Move Doku_Handler to dokuwiki\Parsing\Handler namespace
- File extends Code (shared parsing via $type property)
- Quotes uses mapHandler() + Handler::getModeName() for sub-modes
- Media::parseMedia() replaces Doku_Handler_Parse_Media()
- Code::parseHighlightOptions() replaces parse_highlight_options()
- Per-parse state (footnote, doublequote) stays on Handler
- Deprecated wrappers kept for base/header/internallink/media
- Class alias and rector rules added for backward compatibility

decouple hardcoded mode names in Eol and Preformatted

Eol.php hardcoded ['listblock', 'table'] as modes to skip, and
Preformatted.php hardcoded [\*\-] as a negative lookahead for list
markers. Both embed knowledge that belongs to the respective block
modes, not to Eol/Preformatted. Adding a new block mode that handles
its own EOL or uses different line start markers would require editing
these unrelated files — a hidden coupling.

Listblock and Table now register themselves on ModeRegistry during
preConnect(). Eol queries getBlockEolModes() and Preformatted queries
getLineStartMarkers() to build its lookahead dynamically. Each mode
owns its own data, and new block modes can participate without touching
unrelated files.

SearchIndex: remove write side effect from retrieveRow()

retrieveRow() padded the index file when the requested RID was beyond
the current length. This was an optimization for subsequent changeRow()
calls, but changeRow() already handles padding on its own. The side
effect was also inconsistent with retrieveRows() which is a pure read.

Added a cross-index integration test verifying RID consistency across
entity, token, frequency and reverse indexes when multiple entities
share tokens.

SearchIndex: unify CollectionSearch API and optimize search pipeline

- Remove separate lookup() API from CollectionSearch. All searches now
use addTerm()/execute() with a single unified pipeline.
- Add matches() predicate to Term using efficient string functions
(===, str_starts_with, str_ends_with, str_contains) instead of regex.
- Add caseInsensitive() support on CollectionSearch and Term for
metadata/title searches where indexed values preserve case.
- Remove callback support from MetadataSearch::lookupKey() — the only
real usage (case-insensitive substring) is replaced by
caseInsensitive() + wildcards.
- Remove min-length validation from Term. Add Tokenizer::isValidSearchTerm()
for callers that need it (FulltextSearch, Indexer::lookup).
- Optimize execute() from 4 group passes to 2: scan tokens + resolve
frequencies in one pass per group, batch entity name resolution, then
populate Terms.
- Store full match detail in Term: entity → token → frequency. New
accessors getMatches(), getEntityTokens(), getEntityFrequencies()
derive different views from this single data structure.
- Term no longer used as scratch pad by CollectionSearch. Index-internal
data (token IDs, entity IDs) stays local to execute(). Terms receive
only final resolved results.
- Use title from search results in MetadataSearch::pageLookupCallBack()
instead of re-fetching via p_get_first_heading().
- Update concept.txt documentation.

SearchIndex: rewrite MetadataSearch to use Collection classes

Replace MetadataIndex usage in MetadataSearch with the new Collection/Index
architecture. This completes the read-path migration so data written by the
Collection-based Indexer is read back correctly using TupleOps tuple format.

Generalize FrequencyCollectionSearch into CollectionSearch that works with any
AbstractCollection type (Frequency, Lookup, Direct) and handles both
split-by-length and non-split index layouts transparently. DirectCollection
participates via resolveTokenFrequencies() which maps token RID = entity RID.

Key changes:
- AbstractCollection gains isSplitByLength(), resolveTokenFrequencies(),
getEntitiesWithData(), and groupToSuffix() with validation
- Index groups are now int (0 = non-split, positive = token length)
- CollectionSearch provides both addTerm()/execute() for fulltext and
lookup() for metadata-style search (exact/wildcard/callback)
- MetadataSearch delegates entirely to collection APIs
- Shared filterPages() replaces duplicated page filtering logic
- All callers updated from MetadataIndex to MetadataSearch
- Tests moved to Search namespace with full coverage for new APIs
