KiTTY 0.84.1.54-beta

KiTTY 0.84.1.54-beta

A small parity-and-polish release: Ctrl-Tab reaches the host again for tmux users, a diagnostic-dump redaction gap is closed, and kitty.ini finally has a proper guide.

Highlights:

• Ctrl-Tab and Ctrl-Shift-Tab are passed to the host again (#15). Tab with Ctrl held produces no character message on Windows, so the keystroke was silently swallowed - classic KiTTY mapped the pair to the xterm sequences ESC[27;5;9~ and ESC[27;6;9~, and that mapping had not been carried over into the 0.84 port. It is restored with exactly the classic sequences, so tmux/vim bindings that worked with 0.76 work unchanged. The mapping is skipped in putty-compatibility mode, and KiTTY's own Ctrl-Tab window-switching option, when enabled, still takes precedence.
• Diagnostic dumps: the stored inline login/RuTTY script content is now redacted inside the embedded current.ktx too. The visible /savedump text has redacted it since 0.84.1.37, but the embedded session copy still carried it - that gap is closed, and the long-standing "script-content path under review" caveat is retired from KNOWN-ISSUES.
• New settings-file guide docs/KITTY-INI.md: one page explaining kitty.ini - how KiTTY finds the file, the savemode values and the portable-layout rule, and what each section configures - with the fully annotated kitty.ini.example as the complete key reference. The release pipeline cross-checks the guide against the example, so it cannot drift.
• README refresh: the download notes describe the two ZIP flavours correctly, the stored-passwords summary reflects the portable master password (shipped in 0.84.1.48), the feature digest gained the command console, named proxies/jump hosts, the security set and the kageant capabilities, and the credits link the original PuTTY author's GitHub page.
