Release 0.9.19 "Spirit" - More constants, more space left

This release includes a larger-than-usual number of changes, mostly to
make room for more constants. A side effect is that we gained a lot of
additional space for the DM42, giving us a lot of headroom for future
developments. On the other hand, this may cause unexpected bugs. If
you run DB48x on a DM42, please check for anything out of the ordinary
and report it.

New features
============

* Hierarchical constants library, with astronomy data for planets
* fonts: Add astronomy-related glyphs and a few more
* simulator: RPL evaluation with -e, to preload the calculator
* simulator: RPL console evaluation mode with -E (prints to console)
* simulator: headless mode with -H (no window showing)
* simulator: screen capture with -C for scripting
* simulator: Persist window geometry across runs
* simulator: Persist calculator state on exit
* ui: Enhanced behaviour for EEX key (skips to exponent)
* variables: Store and recall to path
* GCD (GreatestCommonDenominator) and LCM (LeastCommonMultiple)
* Quote command
* Hitting EXIT while editing clears menu

Bug fixes
=========

* variables: Memory corruption when replacing object with subobject
* Fix parsing bug causing partial load of .48k keymaps beyond "@"
* arrays: Strip tags from array and index in `get` and `put`
* solver: Improve solver precision in Std mode
* constants: Correcting the standard uncertainty of several constants.
* constants: Correct the Tau mass relative uncertainty.
* Make sure simulators get the correct help file (distinct .qrc files)
* Show empty menu when entering empty directory in 1-line mode
* Accept decimal / fraction conversions for arrays containing names
* Make it possible to reload `Demo.48s` after initial run on DM42
* Correctly show error message while loading files
* ui: Do not remove `-` when using CHS in an expression like `5-3`.
* bignum: Remove leftover printf statement
* menu: Refresh `CustomMenu` if updated while active
* simulator: Fix race condition in Paste command
* ci: keep Android AABs under `android/`
* ci: package db50x Windows simulator from the correct path
* wasm: bootstrap recorder and host tools correctly
* ci: use libsystre in Windows packaging
* doc: Fix description of simulator -m option
* ids: Fix aliases for EquationValue and XLibValue
* menus: Connect menu entries incorrectly marked as unimplemented
* Fix help topics for various constants / constant groups

Improvements
============

* fw: Move all C / C++ strings to the QSPI on DM42 (save >80K flash)
* tests: Replace `LSHIFT, I` with `ID_ConstantsMenu` for readaibility
* tests: Run cstlib / eqlib tests beyond first error
* tests: Do not save state file after running the test suite
* Do not waste memory while converting`<<`, `>>` and `->`
* Improve rebuild in case of QSPI CRC mismatch
* Enable `make TAR_EXTRA_FILES= install` to install only binaries
* makefile: Generate listing files like the old makefiles
* makefile: Add image comparison targets like in old makefile
* makefile: Avoid extraneous / in paths
* makefile: Pass DB48X_VERSION through the command-line
* debug: Change debug_printf to use all 12 rows
* commands: micro-optimize factorization of cmp == 0 test
* chuck: Make the CHUCK command optional for repeatable builds
* install: Add `DISK_NAME` variables to specify volume name
* ui: Simplify display of alpha and user indicators
* doc: Add information on how to start Fedora on WSL
* ui: Fix misspelling in comment
* doc: Make the age-verification LEGAL-NOTICE more general
* chore(ci): bump packages versions
* doc: Add Pasquale Pigazzini as an author
* solver: Fix compiler warning about signed vs unsigned
* tests: Use `STD` instead of `12 SIG`
* library: Fix comment and remove duplicate entry
* commands: Add `Γ` alias for `Gamma`
* menus: Update and reorganize parts menu
* locals: Detect incorrect argument count in algebraic function calls
* locals: Do not evaluate algebraic expression passed as argument
* version: Update copyright year to 2026
* parser: Accept `,` as a separator in algebraic function calls
* Reorder the constants menu for efficiency
