4203-6.0.7

• fix: startup_views was never cleared after processing, leaking view references and re-running startup detection on a plugin reload
• fix: log squashing could clobber a distinct log line that happened to start with the same text as a repeated one
• fix: is_interpreter's VIM modeline regex had a stray backslash, breaking modelines with trailing options (e.g. # vim: syntax=python ts=4:)
• perf: platform/arch constraints that can never match the current OS are now pruned by the rule optimizer
• perf: merge redundant is_file() + stat() filesystem calls into one on the syntax-detection hot path
• fix: download-dependencies could hang forever on a stalled network connection
• fix: JSON detection heuristic missed content with long leading/trailing whitespace padding
• fix: Emacs modeline detection broke on the standard mode: syntax form
• fix: several constraints violated the rule optimizer's droppable contract, risking incorrect rule pruning
• fix: merge_literals_to_regex() (used by is_interpreter) could drop or corrupt patterns sharing a common prefix
• fix: pref_trim_suffixes() could return an unhashable list instead of a tuple
• fix: a typo'd key in a syntax_rules constraint/match was silently ignored instead of raising a validation error
• fix: explicit null in syntax_rules/trim_suffixes/project settings crashed the settings pipeline instead of being treated as absent
• fix: crash when magika.syntax_map contained an explicit null entry
• fix: typos in the command menu and syntax display names, plus a regex precedence bug in the settings JSON schema
• fix: VIM modeline detection failed to match on the file's last line with no trailing newline
• fix: explicit null config values (modeline_lines, regex_flags, etc.) are now treated as absent; JSON detection now recognizes pretty-printed JSON
• fix: regex constraints with an empty-string or None pattern could match everywhere or match the literal string 'None'
