* Initial plan
* Fix TOML encoder to prefer readable table sections over inline tables
When converting from YAML/JSON to TOML, the encoder now always uses
readable TOML table section syntax ([section]) instead of compact inline
hash table syntax (key = { ... }), which better matches TOML's goal as
a human-focused configuration format.
Changes:
- decoder_toml.go: Mark inline TOML tables with FlowStyle so round-trips
can be distinguished from YAML flow mappings
- encoder_toml.go:
- encodeTopLevelEntry: use FlowStyle check instead of EncodeSeparate to
decide inline vs table section (all block mappings now become tables)
- encodeSeparateMapping: count FlowStyle children as attributes; use
recursive encodeSeparateMapping for nested non-flow mappings
- encodeMappingBodyWithPath: emit non-flow child mappings as sub-table
sections instead of inline tables
- toml_test.go: add encode (YAML→TOML) test scenarios, update roundtrip
expectations for inline tables (now expanded to table sections)

* Fix TOML roundtrip: use TomlInline flag instead of FlowStyle to preserve inline tables
FlowStyle affected YAML decode output (causing inline tables to appear as
YAML flow mappings). Replace it with a new TOML-specific TomlInline bool
on CandidateNode that:
- Is set by the TOML decoder for inline tables (not FlowStyle)
- Is copied by UpdateAttributesFrom so it survives DeeplyAssign merges
- Is checked by the TOML encoder alongside FlowStyle (for YAML flow maps)
- Has no effect on the YAML encoder, preserving existing TOML→YAML output
TOML roundtrip tests are restored to their original expected values (inline
tables stay inline, table sections stay as sections).

* build: pass GOFLAGS to docker to support buildvcs=false
In trying to develop the KYAML support, various tests gave false
positive results because they made assumptions about Git functionality
Make it possible to avoid that by passing GOFLAGS='-buildvcs=false' to
to Makefile.

* build: exclude go caches from gosec
Without tuning, gosec scans all of the vendor/gocache/gomodcache, taking
several minutes (3m35 here), whereas the core of the yq takes only 15
seconds to scan.
If we intend to remediate upstream issues in future; add a seperate
target to scan those.

- Add ShellVariablesPreferences struct with KeySeparator field (default: '_')
- Update shellVariablesEncoder to use configurable separator
- Add --shell-key-separator CLI flag
- Add comprehensive tests for custom separator functionality
- Update documentation with example usage for custom separator
This feature allows users to specify a custom separator (e.g. '__') when
outputting shell variables, which helps disambiguate nested keys from
keys that contain underscores in their names.
Example:
yq -o=shell --shell-key-separator='__' file.yaml
Fixes ambiguity when original YAML keys contain underscores.
- Allow inline maps instead of just aliases
- Allow aliased sequences
- Disallow other types
- Use tag `!!merge` instead of key `<<`
- Fix insertion index for sequence merge
Closes#2386
