v0.1.0

The first release of shell-lsp: a language server for bash, zsh, POSIX sh,
dash, ksh and busybox sh in a single static binary with no runtime
dependencies. The linter, the formatter, the manual-page reader and the
.editorconfig reader are all built in.

Highlights

• zsh is linted by zsh's rules: no bash word-splitting or globbing
  warnings where zsh does neither, zsh's own parameters and hook arrays are
  known, glob qualifiers, parameter flags and subscript flags are
  understood, and #compdef/#autoload files are detected as zsh.
• Full zsh and ksh93 parsing: zsh syntax, from short and brace loops,
  repeat, foreach and { } always { } to anonymous functions with
  arguments, glob qualifiers and math functions, and ksh93's compound
  variables, types, namespace, .sh.math functions and seek redirections
  parse into a full syntax tree instead of syntax errors, through a patched
  fork of mvdan.cc/sh whose patches are kept ready for upstream
  (#23).
• Native linter that reuses ShellCheck's check codes and directives, lints
  zsh, follows sourced files, and adds its own SL checks: untrusted input
  pasted into code run by eval, sh -c or source, opt-in arithmetic
  injection, functions a script never calls, and syntax and regex errors in
  embedded awk, sed and jq programs (docs/rules.md).
• Completion and hover for builtins, keywords, functions, variables and
  paths, plus the options and (nested) subcommands of installed commands, read
  natively from their manual pages, also behind sudo, env, xargs and
  similar wrappers.
• Sourced files act as imports: their functions and globals complete,
  hover, navigate and are followed by the linter; open buffers win over disk.
• Navigation: definition, references, rename, call hierarchy, document
  and workspace symbols, highlights, links, selection ranges, folding.
• Editing aids: semantic tokens (including inside awk, sed and jq
  programs), inlay hints, signature help, code lenses.
• Formatting with the printer shfmt is built on, honouring
  .editorconfig the way shfmt does.
• Quick fixes and refactorings: extract variable or function, inline
  variable, backticks to $(…), [ ] to [[ ]], if/elif to case, toggle
  function, add strict mode, move a function into a sourced file, and a
  fix-all source action.
• Bats: tests in the outline, "Run file" and "Run test" lenses that run the
  project's bats and turn failures into diagnostics that follow their test.
• Fast: whole-file lint of 10k lines in tens of milliseconds, parallel
  workspace indexing, single-flight caching per document version.
