* fix(scripts): make clawlog default behavior match documented usage
Running scripts/clawlog.sh with no arguments was printing the usage help
instead of the documented default behavior (last 50 lines from the past 5
minutes). Remove the early no-args help branch so the defaults are used.
Also validate that options requiring a value (-n, -l, -c, -s, -o) actually
receive one, preventing an unbound-variable abort under set -u.
Fixes#104058
* fix(scripts): preserve dash-prefixed operands in clawlog and add regression tests
ClawSweeper review feedback on #104059 noted that the missing-value
guards introduced in the previous commit also rejected valid operands
beginning with a dash (e.g., search text '-failed' or an output file
named '-debug.log'). Narrow the guards so they only reject genuinely
missing operands, not dash-prefixed values.
Add focused regression coverage in test/scripts/clawlog.test.ts for:
- no-argument default behavior
- missing values for -n/-l/-c/-s/-o
- acceptance of dash-prefixed operands
- --help still printing usage
