v0.8.11

• Performance:
  • Entity inheritance refactored to use lazy parent-chain symbol lookup,
    completely eliminating the copying of object and class maps during
    inheritance. Compile time on a development machine for a 2.4-million-line
    generated source file dropped from ~30 minutes to ~22 seconds.
  • bpp-lsp's ProgramPool now subsumes earlier ASTs when a more complete
    program includes the same file, avoiding duplicate program entities
    and reducing memory pressure
• bpp-lsp:
  • Added -j/--threads option to control the size of the worker thread pool
  • Cross-program entity resolution for references and renaming: we now
    search all programs associated with the given source file for reference
    or when workspace renames were requested
  • Fixed a bug in hover requests where a datamember could be
    misinterpreted as a non-datamember object
  • Handle didSave notifications to free resources that track unsaved
    changed
  • Includes that fail to parse are now tracked, allowing diagnostics to be
    properly updated when the included file is fixed.
  • ProgramPool now supports multiple programs per source file (Closes: #23)
    File changes trigger re-parses and diagnostics for all associated
    programs.
  • Added support for DocumentSymbols requests
  • Shutdown procedure now strictly follows the LSP spec: the server waits
    for an exit notification after acknowledging a shutdown request, and
    exits with the correct (spec-mandated) status codes.
  • ResponseError is now an optional field in protocol messages, in line
    with the LSP spec
• VSCode extension:
  • Added support for the language server's -j/--threads option
  • The -b option (target Bash version) and -j option are now gated behind
    version checks, with a warning when the installed server is too old
• Documentation and spec:
  • New spec page on value categories (lvalues vs. rvalues)
  • Clarified the semantic meaning of 'super', including its behavior
    when explicitly dereferenced
  • Clarified operator expansion rules: replaced ambiguous wording regarding
    the "output" of an operator with a more explicitly-defined statement
    about an operator's "result" and how it expands in shell contexts
  • Corrected wordings in the spec pages for methods and supershells
• Build system:
  • Refactored manpage generation with pattern rules, allowing parallel
    builds. Make target renamed from 'manual' to 'manpages'
• Code hygiene and modernization:
  • Split the monolithic bpp.h header into several smaller, focused headers
  • Removed the internal fake "primitive" class; primitives are now
    represented by class == nullptr, aligning the implementation with the
    language's model
