Fix DuplicateBinding reparse soundness

[dowdiness]

Summary

• Generate DuplicateBinding copy names with lexable numeric suffixes (x1, x2, …) instead of _copy
• Re-indent block-local duplicate insertions so edited text reparses cleanly
• Add reparse-gate wbtests for root and block-local duplicates, plus numeric-suffix collision coverage
• Remove the resolved TODO caveat for Binding duplicate emits non-lexable names (_copy); needs a proper fresh-name mechanism #649/Block-local binding span ops (move/delete/duplicate) produce malformed indentation #650

Fixes #649.
Addresses the DuplicateBinding portion of #650; move/delete indentation remains tracked by #650.

Reuse check

• Reused @scope.enclosing_env to avoid names visible at the duplicated binding.
• Reused scope declarations and existing binding rewrite helpers (binding_rewrite_source, renamed_text) to preserve original source syntax.
• Checked @scope.declaration_for_name_at / @scope.scope_for_node; not used directly for fresh-name generation because duplicate needs a scope-wide collision set, not a single name lookup.

Summary by CodeRabbit

• Bug Fixes

  • Fixed block-local binding duplication to correctly preserve indentation and ensure generated code reparses properly.

• Improvements

  • Enhanced duplicate binding naming mechanism to automatically generate collision-free identifiers instead of using fixed suffixes, preventing conflicts within the current scope.

📝 Walkthrough

Walkthrough

compute_duplicate_binding is rewritten to use a new fresh-name mechanism (base name + incrementing digit suffix) instead of the unlexable _copy suffix, and now computes correct leading indentation for block-local duplicates. Three new helpers are added. All related whitebox tests are updated to assert lexability, reparse correctness, collision skipping, and proper block indentation. The previously noted caveats in docs/TODO.md are removed.

Changes

DuplicateBinding: fresh names and block indentation

Layer / File(s)	Summary
Helper functions and compute_duplicate_binding rewrite lang/lambda/edits/text_edit_binding.mbt	Adds decl_names_in_scope, fresh_name (base+N digit loop), and leading_indent helpers. Rewrites compute_duplicate_binding to derive a collision-free lexable name via fresh_name and to splice the duplicated text with correct leading indentation for block-local bindings.
Root-scope duplicate tests and TODO cleanup lang/lambda/edits/text_edit_wbtest.mbt, docs/TODO.md	Updates root-scope DuplicateBinding tests to expect numeric suffixes (x1, twice1), adds reparse assertions and a collision-skip test (x1 present → x2), and removes the resolved unsoundness caveat from docs/TODO.md.
Block-local duplicate tests lang/lambda/edits/text_edit_wbtest.mbt	Adds a new block-local test confirming a1 generation and correct nested block structure after reparse; reworks the existing block-local suffix-collision test (a1 present → a2) to assert indentation, ordering, and structural correctness via reparse.

Poem

🐇 No more _copy causing a fright,
Fresh digits appended, the names are right!
Block-local indents now line up neat,
Reparsing the output — no corrupted feat.
The TODO grows shorter, the caveats gone,
A cleaner duplicate hops along! 🌿

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'Fix DuplicateBinding reparse soundness' directly summarizes the main change: fixing the DuplicateBinding operation to produce valid, lexable code that reparses correctly.
Linked Issues check	✅ Passed	All coding requirements from issues #649 and #650 are met: DuplicateBinding now generates lexable numeric-suffix names via a fresh-name mechanism, reparse-gate tests verify AST structure, collision handling is tested, and block-local duplicates are re-indented correctly.
Out of Scope Changes check	✅ Passed	All changes are directly scoped to fixing DuplicateBinding: helper functions support fresh-name generation and re-indentation logic, tests verify both reparse correctness and numeric-suffix collisions, and the resolved TODO reflects the fix.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.

Do not mechanically replace this with:
  try expr |> Ok catch { e => Err(e) }

That still creates a local `Result` wrapper and usually misses the intended migration.

Default migration: handle the raising expression directly with `try ... catch ... noraise`, especially in local inspect/assert/match/guard/logging/test code:

  try expr catch {
    e => inspect(e, content=...)
  } noraise {
    value => inspect(value, content=...)
  }

Only create `Ok`/`Err` when the `Result` value must escape this local expression: stored, returned, passed to a Result-taking API, or kept for later comparison as data.

Do not mechanically replace this with:
  try expr |> Ok catch { e => Err(e) }

That still creates a local `Result` wrapper and usually misses the intended migration.

Default migration: handle the raising expression directly with `try ... catch ... noraise`, especially in local inspect/assert/match/guard/logging/test code:

  try expr catch {
    e => inspect(e, content=...)
  } noraise {
