fix(0.10): minor cleanup

[Jint-lzxy]

Sorry for the delay lol this PR includes multiple minor changes that imo are worth incorporating:

• Changed the file mode of all regular files to 100644 (I just noticed that, not sure why our LICENSE is executable lmao)
• Changed ts-context's trim_scope back to outer. My reasoning is that this appears to be a better default for most parsers, as more relevant information tends to come last. For example:

  3 |  namespace utils {
  2 | std::conditional_t<cond, std::chrono::milliseconds, int> function(int lower,
  1 |                                                                   int upper = std::numeric_limits<int>::max()) {

  Most parsers typically generate this kind of hierarchy, with the most relevant bit of information at the very end of the tree. It would be trimmed out if trim_scope is set to inner.

• get_active_clients will only return the clients that are active in the current buffer. Updated the function call to reflect this.
