v0.1.1: Fix Release

A fix release. Every change corrects something 0.1.0 got wrong about a valid model, so a model
0.1.0 rejected or misread may analyze differently here. Nothing was renamed and no interface
changed.

Install: go install github.com/Open-MBEE/OpenSysML/cmd/sysml@v0.1.1, or take a platform archive
below. The Python client opensysml is released separately.

The OMG training corpus reports no errors

• Every definition body inherits the features of the library definition its kind implies. Only
  behavior definitions had an implicit base, so snapshot sale = start; inside a part def
  reported unresolved reference: start even though Items::Item declares start and done and
  Parts::Part redefines both. Two corpus files previously recorded as "bugs in the OMG files" —
  Time Slice and Snapshot Example and Individuals and Time Slices — were never buggy; the
  corpus baseline now lists no files at 100/100 clean.
• A member that reuses an inherited feature's name is now reported instead of shadowing
  silently: part def C { part start; } conflicts with Parts::Part::start. Redefine it to keep
  the name — part start :>> Parts::Part::start;.
• A qualified redefinition of an inherited library feature is accepted.
  snapshot start :>> Parts::Part::start; was rejected as "not an inherited member" when the
  supertype came back from the index cache. Redefining a feature the owner does not inherit is
  still reported.
• A definition may specialize a definition of a comparable kind. individual item def Alice :> Person was refused because Person is a part def; specialization now follows the definition
  taxonomy. Disjoint kinds — a part definition and an attribute definition — are still refused.
• A transition may leave the entry action of the state that declares it. entry action begin { } transition begin then off; reported the action as "not a state or pseudostate"; it now
  designates the machine's initial state and executes as such, and is rendered in a view that
  exposes it. Only that bare completion shape designates a start — a triggered or guarded
  transition out of an entry action, a transition into one, and a name reaching another state's
  entry action or a junction are reported rather than accepted with the trigger, guard or effect
  dropped.
• A metadata usage ends at its own ; or body. @M part def Car; was read as an annotation
  plus an undiagnosed declaration; #M part def Car; is the prefix spelling. A metadata usage
  member also names a type, so @Securty; reports an unresolved reference instead of going
  unchecked, and @M; now parses in a namespace, a body and a state body.
• A value part accepts every operator the grammar allows — = expr, := expr,
  default expr, default = expr, default := expr — wherever a usage, parameter, result or
  subject binds a value.
• The REPL prints a syntax warning once, not once per deferred analysis.

A rendering read at a terminal

• sysml -render writes the text form at a terminal and the machine-readable form of the kind
  rendered — Mermaid for a diagram, Markdown for a table — into a file or a pipe.
  sysml m.sysml -render Views::table showed a Markdown table on screen. > table.md, | tool,
  -o table.md and -render-form are unchanged.
• The text form is ASCII. The rendering header and connection edges used an em dash, which an
  ASCII-only terminal showed as a replacement character.
• A text table is written to fit the terminal, wrapping an over-wide cell rather than
  truncating it or overflowing the window, and narrowing no column below 8 characters. A table
  written to a file or a pipe keeps every column as wide as its widest cell, so a saved artifact
  does not depend on the window it came from.

RDF conversion (experimental)

RDF stays experimental: expressions are still carried as source text, ownership is collapsed rather
than materialized as membership elements, and no round trip against a triplestore has been run yet.
Two changes land here.

• Element IRIs now carry a reversible encoded id instead of the raw qualified name.
  Demo::Vehicle is written as urn:sysmlv2:element:Demo__Vehicle: :: becomes __, _ itself
  escapes to _5f, and any other byte outside [A-Za-z0-9-] becomes _ plus two hex digits, so
  the id is unique, reversible and inside the [a-zA-Z0-9_-]+ character set that a SysML v2 API
  service requires of an element id. Element identity is read from the sysml:qualifiedName
  literal rather than reconstructed from the IRI, so a .ttl written by 0.1.0 still reads back —
  but a graph re-exported from 0.1.1 has different subject IRIs, and anything matching those IRIs
  by string needs updating.
• A reference to an element the graph does not describe is reported with a typed diagnostic
  instead of crashing the converter.
• A metadata usage member is refused with a typed diagnostic rather than written as an
  annotation on a different element.

Documentation and internal quality gates

• docs/ is published as a documentation site built with MkDocs, with the build run in strict
  mode in CI so a broken link or a missing page fails the check rather than shipping.
• The generated SysML OWL ontology table is checked into the tree, with a domain/range gate
  over the exported graphs, derived from the Open-MBEE SysML v2 RDF ontology's 411 property
  declarations. It ships with a committed inventory of the graph shapes that do not yet conform,
  so the remaining work is recorded rather than hidden.
• Static analysis runs on every build through SonarCloud, scoped to hand-written source with
  coverage wired in. The one vulnerability it reported is fixed: the ontology table generator no
  longer resolves git through PATH, reading the checkout's Git metadata directly instead
  (loose refs, packed-refs, detached HEAD, worktrees, and SHA-1 or SHA-256 object ids). The
  generated table is byte-identical, so no recorded commit id changed.
