WIP Changelog

Core

Core updates apply to all components.

Remove special handling of files named tgstation.dme. If needed, set environment in SpacemanDMM.toml.
Parse for-key-value loops (by ZeWaka, #447, and LemonInTheDark, #469).
Fix crash on out-of-range bitshifts in constant evaluation.
Fix bugs with ## token pasting and empty arguments:
- Fix identifiers on the left-hand side of ## being incorrectly dropped (by harry, #471).
- Fix commas on the left-hand side of ## being incorrectly preserved (#411, #192).
Fix preprocessor fexists giving inaccurate results on .dme paths outside the working directory (by ZeWaka, #478).
Mark vector() as a constant constructor (by LemonInTheDark, #468).
Add builtins:
- /icon/proc/RscFile and /sound/proc/RscFile (#416).
- /world/var/process (by forgman6, #456).
Gracefully resume parsing after previously fatal tree-scope parsing errors:
- /var/1 = 1, such as from /var/OPEN = 1 where OPEN is a macro.
- Tree-scope ..(), which has no effect.
- Tree-scope empty blocks, such as from indented block comments, which have no effect.
Improve accuracy of "check for extra indentation" note location on certain rare parse errors.
Optimize parsing by interning keywords and other builtin strings.

Add hover and go-to-definition for /typepath::variable syntax (by ZeWaka, #477).
Add hover for __FILE__ and __LINE__ (by Cyberboss, #358).
Fix go-to-definition failing on variables named list, alist, input, locate, and pick.
Optimize the object tree browser and enable it by default.
Distinguish constants, constructors, and methods in the object tree browser.

Update Auxtools debug server from v2.3.5 to v2.3.8.
Change the default debug engine to Auxtools. Extools is unmaintained since 2021 and support will be removed in a future release.

Fix crash on switch(rand(..)) containing if(x to INFINITY).
Fix undefined vars and procs not being caught if a var or proc with the same name exists globally.
Fix the output type of operator[] calls being the same as the input type (#480).
Improve "unreachable code" warnings to handle continue and break (by LemonInTheDark, #475).
Add SpacemanDMM_should_not_call_parent opt-in warning (by Absolucy, #455).
Add new SpacemanDMM_should_not_sleep modes, configured by setting dreamchecker.sleep_analysis_version:
- sleep_analysis_version = 1 is the old default.
- sleep_analysis_version = 2 catches many more cases but has false positives (by CabinetOnFire and Cyberboss, #472).
- sleep_analysis_version = 3 catches a few more cases than 1 but has many fewer false positives than 2, and is the new default (by ZeWaka, #479).
Add flag definitions for filter(type="displace") (by Krashly, #445).
Add warning for using the indexing operator on types without proc/operator[] (by LemonInTheDark, #397).
Add warning for list.Find() with no arguments (by ZeWaka, #460).

Fix loading .dmi icon states with backslashes or quotes in their name, such as in fonts.
Add icon-smoothing-2025 render pass to support tgstation's newest system (by Absolucy, #454).
Optimize blitting somewhat.
