build(deps): update python-hcl2 requirement from >=8.1.3 to >=8.1.4

[dependabot]

Updates the requirements on python-hcl2 to permit the latest version.

Release notes

Sourced from python-hcl2's releases.

v8.1.4

What's Changed

Fixed

• Parse blocks whose type or unquoted label is an HCL keyword, such as the in block in Snowflake's snowflake_schemas data source. HCL reserves no keywords, so all are now accepted as block labels. Diagnosed independently in #355. (#357)
• Parse keyword-named object keys reliably, fixing a regression of #148. A key such as in parsed only where the lexer fell back to NAME, so its separator and position decided whether the file parsed. (#357)

Changelog

Sourced from python-hcl2's changelog.

[8.1.4] - 2026-09-08

Fixed

• Parse blocks whose type or unquoted label is an HCL keyword, such as the in block in Snowflake's snowflake_schemas data source. HCL reserves no keywords, so all are now accepted as block labels. Diagnosed independently in #355. (#357)
• Parse keyword-named object keys reliably, fixing a regression of #148. A key such as in parsed only where the lexer fell back to NAME, so its separator and position decided whether the file parsed. (#357)

[8.1.3] - 2026-08-26

Several fixes below change the values loads() returns for input that already parsed without error in 8.1.x — negative integer literals, both strip_string_quotes behaviours, and the two heredoc body fixes. The previous result was a bug in each case, so this stays a patch release; re-check your expectations if you built around the old values.

Fixed

• Restore py.typed marker so type checkers recognize hcl2 (and cli) as typed packages. (#299)
• Parse heredocs with an empty body again. A marker immediately followed by its closing delimiter failed to match, and the lexer then ran on to a later delimiter, silently absorbing the attributes in between. Thanks, @​livingstaccato (#312)
• Negative integer literals load as numbers again instead of ${-N} expression strings, matching negative floats and the pre-8.x behaviour. Thanks, @​livingstaccato (#311)
• strip_string_quotes no longer unquotes string literals nested inside expressions, which produced invalid HCL such as ${upper(x)} from upper("x"). Thanks, @​livingstaccato (#313)
• strip_string_quotes now resolves escape sequences, so the values it yields match what the option documents. Escapes naming a codepoint outside the Unicode range, or a lone surrogate, are preserved verbatim rather than raising. Thanks, @​livingstaccato (#313)
• Parse files with CRLF (\r\n) line endings, including heredocs. A \r acting as part of a line ending is ignored, so a CRLF file reconstructs with LF endings; a \r that is content — inside a quoted string or a heredoc body — is preserved. Thanks, @​agu2347 (#317)
• Flattened heredoc bodies keep their trailing blank lines and trailing spaces instead of being right-stripped away, for both <<MARKER and <<-MARKER. The closing marker line's own indentation is still removed, and a blank line no longer cancels the <<- dedent. Thanks, @​agu2347 (#318)
• Parse heredocs whose delimiter is a single character, such as <<E. The spec defines the delimiter as an Identifier, which permits one character. (#323)
• preserve_heredocs=False combined with strip_string_quotes now returns the heredoc body as a plain multi-line string instead of escaping every newline to a literal \n. The escaping is still applied to the quoted source form produced without strip_string_quotes. (#324)

[8.1.2] - 2026-04-10

Fixed

• true, false, and null now serialize to native JSON types instead of strings. (#293)

[8.1.1] - 2026-04-07

Added

• v7-to-v8 migration guide and absolute GitHub links in README docs table. (#287)

[8.1.0] - 2026-04-07

Added

• Full architecture overhaul: bidirectional HCL2 ↔ JSON pipeline with typed rule classes. (#203)
• hq read-only query CLI for HCL2 files (#277)
• Agent-friendly conversion CLIs: hcl2tojson and jsontohcl2 (#274)
• Add template directives support (%{if}, %{for}) in quoted strings (#276)
• Support loading comments (#134)
• CLAUDE.md (#260)
