• chore: sync pnpm-lock.yaml with package.json

  Lockfile was missing entries for tree-sitter language parsers
  (c-sharp, cpp, go, java, php, python, ruby, rust) that were already
  declared in packages/core/package.json.

• fix: allow /understand to target an arbitrary directory path

  Previously, PROJECT_ROOT was always set to CWD, which broke on
  alternative CLIs (e.g. OpenClaw) that set CWD to their own workspace
  directory. Now Phase 0 parses $ARGUMENTS for a non-flag directory path
  and uses it as PROJECT_ROOT, falling back to CWD when omitted.
  
  Closes #90

• fix: PHP namespace block extraction, C/C++ language split, and Lua config

  - Handle block-scoped PHP namespaces (`namespace Foo { class Bar {} }`)
    by recursing into compound_statement bodies in PhpExtractor
  - Separate C (.c/.h) from C++ (.cpp/.cc/.hpp) into distinct language
    configs so .c/.h files resolve to language "c" instead of "cpp"
  - Add Lua language config so .lua files resolve to "lua" instead of
    "unknown" after the EXTENSION_LANGUAGE map was replaced by LanguageRegistry
  - Update TreeSitterPlugin JSDoc to reflect all 10 supported languages

• refactor: move TS/JS extraction logic to TypeScriptExtractor, dispatch via LanguageExtractor interface

  Extract all TypeScript/JavaScript-specific AST extraction functions
  (extractParams, extractReturnType, extractImportSpecifiers, processTopLevelNode,
  extractFunction, extractClass, extractVariableDeclarations, extractImport,
  processExportStatement, and call graph walking) from TreeSitterPlugin into the
  new TypeScriptExtractor class. TreeSitterPlugin now dispatches to registered
  LanguageExtractor instances, defaulting to TypeScriptExtractor for backward
  compatibility. All 426 existing tests pass unchanged.

• refactor: replace hardcoded EXTENSION_LANGUAGE map in GraphBuilder with LanguageRegistry

  GraphBuilder maintained its own ~60-line extension-to-language mapping that
  duplicated and could diverge from the canonical LanguageRegistry. Now delegates
  language detection to LanguageRegistry.getForFile(), eliminating the duplication
  and ensuring new language configs are automatically picked up everywhere.

• fix: include access token in auto-opened dashboard URL

  CLI --open overrides server.open config, stripping the token. Remove
  --open from CLI and set server.open to /?token= so the browser opens
  with the access token already included.

• redesign: full homepage refresh with gradient keywords, new problem section, and improved visual hierarchy

  - Hero: gradient "Understand" headline, badge pill, staggered entrance animations, star icon for GitHub
  - New Problem section: structure vs meaning comparison with hairball SVG and domain preview cards
  - Showcase: split into structural (table stakes) and business knowledge (star) with pill labels and feature tags
  - Features: 2-column layout with gradient icons and tighter copy
  - Install: copy-to-clipboard button
  - Footer: expanded with Live Demo link and updated tagline
  - Global: rose-gold-to-gold gradient tokens, .grad text utility

• refactor: extract addChildNode helper to remove repeated boilerplate

  All five child-node loops in addNonCodeFileWithAnalysis shared the same four-line pattern: dedup check, nodeIds.add, nodes.push, and a contains edge push. A private addChildNode helper centralises this so each loop only constructs the node object specific to its type.

• fix: use localeCompare in languages sort for reliable alphabetical order

  Default sort() uses Unicode code point ordering which can produce unexpected results for non-ASCII strings. localeCompare guarantees correct alphabetical ordering regardless of character set.

• refactor: return shallow copies of nodes and edges from build()

  build() was returning direct references to the builder's internal arrays, allowing callers to mutate graph.nodes or graph.edges and corrupt the builder's state. Spreading into new arrays at build time prevents this at negligible cost.

• refactor: deduplicate import and call edges via edgeKeys set

  addImportEdge and addCallEdge previously pushed edges unconditionally, allowing duplicate relationships if multiple agents reported the same import or call. A shared edgeKeys set keyed on type|source|target silently skips any edge that has already been recorded.

• refactor: extract endpoint label into variable to avoid duplicated template

• refactor: return fileId from addNonCodeFile instead of recomputing it

  addNonCodeFileWithAnalysis was reconstructing the fileId string independently of addNonCodeFile, creating a silent correctness risk if the ID construction logic ever changed. addNonCodeFile now returns the ID it used so the caller cannot go out of sync.

• refactor: extract basename helper to replace repeated split/pop pattern

  The same filePath.split("/").pop() ?? filePath expression appeared three times across addFile, addFileWithAnalysis, and addNonCodeFile. A private static helper centralises the logic and makes call sites easier to read.

• refactor: promote nodeIds to class field to avoid O(n²) set rebuild

  Previously addNonCodeFileWithAnalysis rebuilt a full Set from this.nodes on every call, making duplicate checks O(n) per file and O(n²) overall. Moving nodeIds to a class field and updating it incrementally at each insertion reduces duplicate detection to O(1) per check.

• refactor: extract KIND_TO_NODE_TYPE as module-level constant in GraphBuilder

  d16b27eb20
• fix: add plugin manifest under understand-anything-plugin/.claude-plugin

  marketplace.json declares plugins[0].source as ./understand-anything-plugin,
  so Claude Code resolves the plugin manifest at
  ./understand-anything-plugin/.claude-plugin/plugin.json. That file did not
  exist — only .claude-plugin/plugin.json at the repo root — causing
  "Marketplace sync failed. Some plugins in this marketplace have validation
  errors." when adding the marketplace via /plugin marketplace add.
  
  Adds the manifest at the path the marketplace source expects, so marketplace
  sync validates and the plugin can be installed. Version matches the current
  root plugin.json (2.3.1).
