contrib: Add bash completion for new bitcoin command #33385

1. 
   caesrcd commented at 3:34 pm on September 13, 2025: none

   Adds a bash completion script for the new bitcoin command-line tool (introduced in #31375), which unifies the main Bitcoin Core executables under a single interface. This feature improves usability, reduces errors, and makes the command-line tools more easily discoverable for users working in a Linux bash environment.

   The completion script dynamically lists available commands and options by parsing bitcoin --help and bitcoin help. It also incorporates the existing bash completions for bitcoind, bitcoin-cli, and bitcoin-tx, depending on the argument provided (node, rpc, or tx). This ensures that all relevant completions are available seamlessly through a single interface without modifying core functionality.

   Key points:

   • Improves developer and user experience on the command line.
   • Does not modify or replace existing functionality.
   • Placed under contrib/ for easy installation by users and distributions.

   Possible typos and grammar issues:

   • senseful -> sensible [nonstandard word “senseful” should be “sensible” to be clear]
   • save and use original argument -> save and use the original argument [missing “the” makes the phrase slightly ungrammatical]

6. contrib: Add bash completion for new bitcoin command

   Adds a bash completion script for the new bitcoin command-line
   tool, which unifies the main Bitcoin Core executables under a
   single interface. This feature improves usability, reduces errors,
   and makes the command-line tools more easily discoverable for users
   working in a Linux bash environment.
   
   The completion script dynamically lists available commands and options
   by parsing `bitcoin --help` and `bitcoin help`. It also incorporates
   the existing bash completions for `bitcoind`, `bitcoin-cli`, and
   `bitcoin-tx`, depending on the argument provided (node, rpc, or tx).
   This ensures that all relevant completions are available seamlessly
   through a single interface without modifying core functionality.
   
   No functional changes to core code are introduced; this is an optional
   enhancement placed under `contrib/` for easy installation and use.
