feat: replace git-release with makerelease.sh

Add a new release helper that supports clean-tree checks, dry-run mode, and semantic version increments from the latest tag. Remove the old git-release script and update project conventions to reflect the new release workflow.

 - Keep shell scripts Bash-based when Bash is already used by the project.
 - Preserve the current behavior of the main scripts:
   - `sshrm`: remove an entry from `~/.ssh/known_hosts` by host name or by line number.
-  - `git-release`: handle releases from `dev` to `main`, create an annotated tag, and push commits and tags.
 - Keep user-facing messages short, clear, and in English.
-- Prefer minimal, focused changes that do not alter the intent of the existing scripts.
+- Prefer minimal, focused changes that do not alter the intent of the existing scripts, unless the script behavior is intentionally updated.
 - Maintain `.continue/rules/project.md` whenever project conventions or script behavior change.
 - `sshrm` is implemented as a small Bash script with helper functions, while preserving host and line-number removal behavior.
 - `sshrm` should print a short usage line, support `-h`/`--help`, and fail clearly on missing or invalid line-number input.

+Creates an annotated Git tag from the current dev branch.
+
+If VERSION starts with +, it is treated as an increment:
+- +0.0.1 increments patch
+- +0.1 increments minor
+- +1 increments major
+
+Use --dry-run to show the computed release version without running Git actions.
+
+Requirements:
+- run from a clean Git working tree
+- current branch must be dev for real releases
+- main branch must exist locally
