chore(deps): bump @o3co/ts.hocon from 1.1.0 to 1.2.0

[dependabot]

Bumps @o3co/ts.hocon from 1.1.0 to 1.2.0.

Changelog

Sourced from @​o3co/ts.hocon's changelog.

[1.2.0] - 2026-05-18

Notes

• Substitution and top-level quoted strings continue to accept \uXXXX escapes producing surrogate code units (Java/Lightbend semantics). This intentionally diverges from rs.hocon, which rejects them because Rust's char cannot represent unpaired surrogates. See spec "Surrogate codepoint divergence" note.

Changed

• BREAKING: Minimum Node.js version raised from 18 to 22 (engines.node is ">=22"). Node 18 reached EOL on 2025-04-30; Node 20 reached EOL on 2026-04-30. npm install on Node ≤ 21 will emit EBADENGINE and refuse to install.
• BREAKING (S8.6): a = -foo, a = -bar, a = - and other --not-followed-by-digit inputs are now lex errors. Per HOCON.md L270–276, a leading - must begin a number literal (i.e. be followed by a digit). Previously these were silently accepted as unquoted strings ("-foo", "-"). Mitigation: quote the value (a = "-foo"). Note: this is intentionally stricter than Lightbend's reference implementation, which falls back to unquoted on number-parse failure. Digit-leading inputs (e.g. 123abc, 01, 1e+x) are unaffected — ts.hocon's token model has no separate number kind, so the resolved value continues to match Lightbend's value-concat output for the common cases (see docs/spec-compliance.md §S8.6 for the remaining gaps tracked under #73).
• Substitution body tokenization: ${...} internals are now tokenized at lex time via parseSubstBody. SubstPlaceholder.segments is now Segment[] (each segment carries text, line, col). The opt_subst token kind has been removed — use token.subst.optional instead.
• Key parser now handles mixed quoted/unquoted paths like a."b.c".d in both key position and substitution paths.

Fixed

• Escape expansion and whitespace concatenation inside substitution paths now match Lightbend behavior (closes #58). Example: ${"a" "b"} produces a single-segment path with text "a b"; ${"a\nb"} produces a newline in the segment text.
• parseSubstPath (resolver-level re-parse) removed; substitution segments now flow directly from the lexer without a second parse pass, eliminating a class of subtle position and escape-handling bugs.
